Piston Check Valve Features and Benefits

– Plug type and ball type design
– Plug and seat are grinded and lapped to a mirror finish and tightly guided to prevent dragging and seat damage
– Body and cover joint accurately machined with high surface finish sealing chamber
– Low emission valve technology with a design optimized for extended service life
– Seal ring construction for excellent sealing
– Low pressure cracking
– High flow capacity, minimize flow velocity

Applications for Piston Check Valves

Red Point’s piston check valves can be deployed for a wide variety of applications in the oil & gas and (petro)chemical industries when high quality and highly reliable valves are required. A few example applications include:

• High-temperature services
• High-pressure oxygen, nitrogen or hydrogen
• Solids handling (powders, fines, dust and catalysts)
• Polyethylene or polypropylene
• Coal conversion and gasification
• Thermal fluids
• Separator, filter and drying systems
• Compressor stations
• On/off isolation service
• Oil and gas manifolds
