Product Features
- Dual Plate Check Valve as the most efficient & versatile design.
- This valve is suitable for low-velocity applications with infrequent velocity reversals.
- This design offers the twin advantages of No Water Hammer and NonSlam together.
- Dual Plate design minimize valve cracking pressure and reduces valve pressure drop.
- Spring loading on plate assists valve closing to ensure a tight seal and minimize slamming.
- When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place.
- Dual Plate Check Valves are automatic in operation and designed to prevent reversal of flow in fluid piping systems.
- These valves are maintained open by the flow of fluid in the straight direction and are closed by the back pressure of the fluid.
- The valve can be fitted with external weights to allow the faster closure to reduce water hammer or shock pressure on flow reversal.
