Different Types of Check Valve and Its Applications


Check valves are designed to pass flow the fluid in one direction with minimal resistance and prevent reverse flow or damage to the passage. Check valves are the most important valves included in any system, whether household or industrial system. Different Check valve Types are designed for different applications.

How does Check valve work?

A check valve is constructed with a valve body, cover, and disc attached to a hinge and swings away from the valve seat to allow the flow of the fluid passing.

Types of Check Valves:

1. Swing Check Valve

The disc is unguided in a Swing Check Valve, when it moves to fully open position or to a fully closed position the fluid flows in a forward direction with minimal resistance. Many different discs and seat designs are made available by SKG Pneumatics to satisfy requirements of varying applications.

2. Ball Check Valves

Ball Check valves are constructed with a spherical ball inside the body which helps to control the flow of the fluid. The ball rotates freely when the fluid is passing by. This unique process makes it ideal for installing it for a viscous fluid.

3. Tilted Check Valves

A tilted check valve is designed with a disc which has a pivot point at the center of the disc. When the flow is streamed the disc open and when it turns to reverse the disc closes immediately. This Tilted Check valve is mostly used in agricultural areas.

4. Dual Disk Check Valve

A dual disk check valve is designed to control the flow of the fluid, the hinge is connected to a plate which rotates and the stream is controlled when the hinge is moved.

5. Silent Check Valve

This check valve availed by SKG Pneumatic are designed to eliminate water hammer and are recommended to use in multi-story buildings. It consists of a spring attached to the disc which slowly closes when the water flow decreases, eliminating the hammering.

6. Nozzle Check Valves

Nozzle check valves are designed to stream the flow of gas, fluid or slurry in low pressure. This check valve doesn’t allow reverse stream as it closes when low pressure is felt than actual.

SKG Pneumatics is the solution to your all piping system including also Industrial Valves. These are some non-return valve designed and supplied by SKG Pneumatics accompanied by Advance, Zoloto, NVR, etc to maintain the safety and better piping system.

Different Types Of Hydraulic Valves

Hydraulic valves direct any type of flow of liquid medium through a hydraulic system and control the flowing fluid. There are different systems utilized in hydraulic to enable this to happen. Valves can be precisely worked (by handle, handle or cam), electric solenoid-worked, or pilot-worked (air or water powered weight incites the valve). A few valves utilize the weight of the circuit’s liquid to activate themselves, as with alleviation valves. Valves can likewise be incited with links, switches, plungers, torque engines, etc. There are many industrial valves supplier in the market which provides different types of valve for various purpose in which the most common valve the use water valve. Here some other valves which we supply to our clients.

Hydraulic Pressure Reducing Valve

Hydraulic pressure valve exerts its pressure by the hydraulic fluid in all the direction and exerts the force per unit area. Thus hydraulic pressure is used in various hydraulic systems like jaws of life, metal shears, automobile brakes, car crusher etc.

Butterfly Valve

A valve comprising of a pivoting round plate or a couple of pivoted half-circle plates appended to a transverse shaft and mounted inside a pipe so as to manage or forestall stream. Butterfly valves work comparatively to ball valves. Pivoting (rotating) the handle, either physically or with a pneumatic framework, turns the plate opposite or parallel to the stream of the liquid.

Hydraulic and Pneumatic Valve

A solenoid valve is an electrically enacted valve, regularly used to control the stream or heading of air or fluid in liquid power frameworks. Solenoid valves are utilized in both hydraulic pressure and pneumatic pressure power system, and regularly in either poppet or spool arrangements.

Check Valve

A check valve, non-return valve, reflux valve, maintenance valve or single direction valve is a valve that ordinarily permits liquid (fluid or gas) to course through it in just a single bearing.

Globe valve

It has a unique relation to ball valve, is a sort of valve utilized for controlling stream in a pipeline, comprising of a portable plate type component and a stationary ring seat in a for the most part round body. These globe valves are generally used in the petroleum industry.

Ball valve

A ball valve is a type of quarter-turn valve which utilizes an empty, punctured and rotating ball to control move through it. It is open when the ball’s gap is in accordance with the stream and shut when it is turned 90-degrees by the valve handle. The handle lies level in arrangement with the stream when open, and is opposite to it when shut, making for simple visual affirmation of the valve’s status.

Ball valves are solid, performing great after numerous cycles, and dependable, shutting safely even after extensive stretches of neglect. These characteristics settle on them a brilliant decision for shut off and control applications, where they are frequently linked to doors and globe valves, yet they come up short on their fine control in throttling application.

Pressure Reducing Valves – Applications & Installation

Pressure Reducing Valves or more commonly Water Pressure Reducing valves lower the pressure of in rushing water/ steam/fluid to a manageable and predetermined level usually at a constant level to make it safer. Utilized in residential, commercial, institutional, and industrial installations the downstream pressure is ensured through a pressure adjustment valve setting. The modern models also incorporate an external sensor for the same purpose. Similarly, the Pressure Independent Control Valve (PICV) includes a tiny diaphragm type DPCV to ensure a constant differential pressure across the opening such that a constant flow rate is maintained.

Pressure reducing valves are categorized into two types — direct acting and pilot operated. These employ globe or angle style bodies. Direct-acting valves have gained more popularity as they comprise globe-type bodies with a spring-loaded, and a heat-resistant diaphragm linked to the outlet valve that connects a spring. The spring, on the other hand, presets tension on the valve seat that is a pressure-equalizing mechanism in order to gain precise water pressure control.

INSTALLATION STEPS FOR PRESSURE REDUCING VALVES  

  1. Determine first the inlet water pressure. Attain it BY ATTACHING  A PRESSURE GAUGE TO HOSE SILL Cock. Ideal house water pressure should be measured at around 50 PSI.
  2. In case pressure exceeds excessively, install the pressure-reducing valve.
  3. Using threaded pipe and fittings, attach a pressure gauge, an initial step to the pressure-reducing valve at each side.
  4. Place the pressure-reducing valve assembly against water pipe to draw the mark for cutting the pipe.
  5. After Shut off the water mains, drain water from the piping system.
  6. Employ a tubing cutter for removing a water pipe section, from the marks made in Step 4.
  7. Remove from valve assembly both the pressure gauges and rubber O-rings.
  8. Brush flux the valve assembly ends onto the ends of the water pipe.
  9. Solder valve assembly to the water pipe as part of the piping system that is made of copper.
  10. Reinstall the pressure gauges and O-rings, after assembly cools.
  11. After turning on the water take a reading of the pressure gauge placed on the outlet side of the valve.
  12. In case water pressure is above 50 PSI (too high), the adjusting screw on the valve should be turned counterclockwise.
  13. On the other hand in case the water pressure is less than 50 PSI ( too low )  the adjusting screw on the valve should be turned clockwise.

 

The same installation can follow all similar steps including pressure control valve, water prv.

In hydraulics, a pressure reducing valve serves the same purpose as a pressure regulator valve in a compressed air system and will lessen the pressure in one branch but enable full system pressure operations at other branches. Installed directly after the water meter in homes, commercial buildings, and industrial plants, a ( water) pressure reducing valve automatically reduces the pressure to a lower, more utilizable pressure from the main supply.

SOME OF ITS APPLICATIONS ARE:-

  • Protecting electric hot water storage heaters and household appliances
  • Building and domestic installations
  • Collective installations
  • Industrial installations

 

 

Wafer And Lug Type Butterfly Valves

Butterfly valves are generally used in chemical or food industries to regulate or isolate the flow of liquid, gas and solid. The valve manufacturers are in high demand and new companies of valve manufacturers are rising in the market rapidly. We as SKG Pneumatics Inc, Butterfly Valve Suppliers and Industrial Valve dealers in India offer high-quality valve as the demand is growing.

TYPES OF BUTTERFLY VALVES AND DEMAND

POPULAR BUTTERFLY VALVES

When it comes to the butterfly valve, there are four types including Wafer type end, lug type ends, butt welded type ends and both flanged ends. They have a wide demand in several industries like sugar, oil, chemical industries etc. Butterfly valves, mainly the wafer valves and lug type valves are always tested to meet industrial requirements.

DIFFERENCE BETWEEN WAFER AND LUG TYPE VALVES

The wafer body type valve is easy to install but cannot be used as the isolation valve. They don’t have attachment lugs. On the other hand, Lug type valves have lugs attached to the flanges on the end and can be removed easily.

DEMAND OF BUTTERFLY VALVES

Butterfly Valves are in high demand because these valves can be used even in high-pressure services. Butterfly valves need less time to open and close, thus maintenance costs compared to other valves like ball valves.

ADVANTAGES OF BUTTERFLY VALVES

Due to its lightweight design and compact nature butterfly valves is suitable as compared to other valves. They are most popular and high in demand among the Valves Suppliers in Delhi.  They can be widely used in cooling water, fire fighting, vacuum services with good performance.

OTHER TYPE OF BUTTERFLY VALVES EXCEPT FOR THE WAFER AND THE LUG

While the wafer type cannot be used as a pipe end, lug type can be used as a pipe end. The other two form of butterfly valves mainly the welded one is used for high-pressure applications.

With the demand of valves growing in the Indian market other valves like balancing valves, a globe valve, ball valve has also increased. Although, butterfly valves still remain the most popular particularly because of its low cost and easy installation.

Types of Pipe valve

A valve is a device that can control the flow and pressure of the fluid in a pipe. A few either starts or altogether stops the flow of fluid whereas there are some that partially obscures the path.

The different types of pipe valves are explained below in detail.

Ball Valves

Ball valves operate with a quarter-rotary motion. In a ball valve, the flow path is manipulated by the ball-shaped disk which requires a 90-degree turn of the valve handle. It is comparatively smaller in size and lighter than a gate valve.

Butterfly Valves

Butterfly valve can start, stop, and regulate the flow path but only to some extent. It is a simple valve that can be operated by a 90-degree turn of the valve handle. A butterfly valve is not normally designed to give a positive shut-off but modern technology has provided room for improvement in its blueprint. This valve is now capable of a bubble-tight shut-off.

Check Valves

Check valves, or NRVs (non-return valves), supports the unidirectional flow of fluid only. Their function is to check backflow. In check valves, backflow is prevented by “stoppers”. The different kinds of “stoppers” are ball, piston, and swing. Ball and piston check valves work by demanding a little amount of inbound flow pressure. The movement of fluid in a swing check valve is through a pivoting flap which opens only in one direction and ensures that there is no backflow.  

Gate Valves

Gate valves are the most ordinary and the most frequently sold valve type in the industrial valve trade. These act as a block valve for isolating pipe systems since their properties are limited to either opening or closing. There is no restriction in the flow path once a gate valve is opened as it opens all the way. Gate valves are preferred in a straight-line system that requires minimum obstruction. You can regulate a gate valve with the help of a hand-wheel or a piston actuator.

Pressure Reducing Valves

If you are looking for a device to reduce the water pressure, pressure reducing valve is your answer. These valves get down to work by bringing down the quantity of water that flows through a pipe. With the valve, water that was pushing through the pipes at high pressure will be efficiently slowed down.
