Dual-plate check valves (Proquip)
Overview
Category: Gate, globe, and check valves
- 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
