Refer Swing Check Valve Sizes and Dimensions
Leading supplier and exporter of pilot operated check valve in 10000 PSI rating
Check valve is basically a type of direction control valve which primarily used to control the direction of the fluid in hydraulic system. It is a unidirectional valve it only allows liquid to flow in one direction. Fit-lok is trusted Check valve manufacturer in India in size range of 1/2″ to 2″. We don’t compromise in terms of quality of material while manufacturing Swing Check Valve, Raw material is sourced from trusted and certified suppliers.
Pilot operated check valve inexpensive and easy solution for the potential issue which media backflow can cause. Backflow of media can cause contamination of upstream media, it can cause damage to equipment, it could increase a maintenance costs and system inefficiency.
Flow of media in Hydraulic check valve remain steady as long as the pressure is sufficient to keep the disc open, once the pressure drops, the disc automatically returns to its seat, which shut off the flow. The pressure required to open the high pressure check valve is known as cracking pressure which typically ranges between 3 psi to 350 psi depending on the size of valve. These valves create a tight seals to prevent any leaks.
Female X Female Check Valve has threads on both the ends. These valve can withstand pressure upto 15000 PSI. We are one of the leading double check valve supplier in India and can supply it to countries like Nigeria, UAE and South Africa. We keep ready stock of female non return valve in pressure range of 3000 PSI to 20000 PSI. These valves are tested using various destructive and non destructive methods to ensure the quality of products.

Water hammer can be avoided by employing check valves that close rapidly, thus avoiding pressure surges and shock waves. Silent check valves are one of the effective solutions to this problem.
Advantages
- Prevent backflow
- Self-actuated
- Prevent water hammer
- Reduce sudden valve failure
- Lower maintenance costs
- Few moving parts
- Smaller footprint
- Do not require power to operate
Disadvantages
- Do not operate in pulsating systems
- Noise from slamming discs
- Reverse flow problems
- Operate in a completely enclosed system
- Internal parts cannot be checked
