Dual Plate Check Valve Features and Benefits
– Retainerless valve body; meaning, no penetration through the body wall
– Fire safe design
– Self-seating design that reduces dragging along the seat surfaces
– Lapped seating surfaces that exceed API 598 seat leakage requirements for metal-seated valves
– An uninterrupted gasket surface
– Shock bumpers minimize shock-force on internal components
– Immediately responsive spring design to changes in flow characteristics
– Low pressure cracking
– High flow capacity, minimize flow velocity
Applications for Dual Plate Check Valves
Red Point’s dual plate 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
