Male to Female NRV Check valves are commonly found protecting pumps in liquid applications or compressors in gas systems where backflow could cause the pump or compressor to shut down. They are also applied in process systems that have varying pressures, which must be kept separate. They do not need an outside power supply to operate since they use the pressure drop created by the media flow.
1. Check valves are used to prevent backflow and maintain pressure.
2. They are commonly used as: a backup in case a pump fails, to help compressors and reciprocating pumps function, and when the system pressure exceeds the primary equipment capabilities.
3. Check valves can be seen in industries such as refining, petrochemical, chemical, etc., oilfield production, water, steam, refining petro, and viscous fluids.
4. Check valves are also commonly found in waste-water management systems and in manufacturing
