A check valve is a mechanical device that is used to prevent backflow in a piping system. In other words, check valves obstruct the fluid flow in one direction and enables unobstructed flow in the opposite direction. The check valve is also commonly known as a non-return valve (NRV) or a one-way valve.
Check valves have two openings in the body, one for the entry of the fluid and another for an exit. Check valves are largely used in household items, however, they also serve a great purpose in controlling the direction of fluid flow in hydraulic systems. Since there are too many check valve suppliers in India, you need to find the one who provides industrial quality check valves.
What is a Hydraulic System?
Most industries require a controlled application of force and these operations are usually carried out using electrical or fuel-based machines as a prime mover. However, specially designed enclosed fluid systems can also provide controlled motion and force to the substances. These systems are capable of providing both linear as well as rotary motion and it also allows us to apply high magnitude controlled force. This kind of enclosed fluid-based system that uses pressurized incompressible liquids as transmission media is known as a hydraulic system.
What are Hydraulic Control Valves?
A hydraulic control valve is a device that has the capability to change the opening degree of the fluid flow path. Additionally, control valves are also used to regulate the speed of the fluid flow to the motors and cylinders.
Most common Hydraulic control valves types
- Directional control valves
- Pressure control valves
- Flow control valves
These hydraulic valves can be controlled by manual, mechanical, hydraulic, electric, electro-hydraulic, pneumatic, and input control, on or off fluid flow channels.
What is the importance of check valves in Hydraulic Systems?
Check valves serve a variety of purposes in hydraulic systems. It is important because:
- It blocks pressure spikes
- Prevents oil lines from draining
- Blocks oil flow from the accumulator
- Prevents oil flow from the online pump to the offline pump
Check valves help you prevent backflow in a hydraulic system while control valves help you regulate the speed of the fluid flow in the hydraulic system. With all the different types of hydraulic valves, you need to choose the right one in order to get the job done.
