Dual Plate Wafer Check Valve

Dual Plate Wafer Check Valve Suppliers in Saudi Arabia: Space-Saving Backflow Prevention

Middleeast is the largest Dual plate wafer check valve suppliers in Saudi Arabia. It is a type of check valve that consists of two plates that are hinged together.

Components:

1. Valve Body (Wafer Design) – lightweight and compact, fits between standard flanges
2. Dual Plates/Discs – swing open while moving forward and close while moving backward
3. Spring Mechanism – ensures rapid closing to reduce water hammer
4. Seat – creates a snug seal to avoid leakage
5. Stop Pin and Hinge – guide and control the disc action

Working Mechanism:

As the liquid flows in the direction of motion, pressure elevates the two plates from the center, ensuring smooth flow. Upon cessation of flow or a reversal of direction, the torsion spring swiftly pushes the plates to the closed position, blocking backflow and safeguarding downstream equipment from destruction.

Advantages:

• Lightweight and compact structure
• Simple mounting between flanges
• Rapid response to reversed flow
• Eases water hammer and pressure pulses
• Low pressure drop and high flow rate efficiency
• Maintenance and corrosion-resistant
