DUAL PLATE CHECK VALVE SUPPLIER IN INDIA 

Speciality Valve is one among leading Dual Plate Check Valve Supplier in India offering dependable, high-performance solutions for sensitive fluid control operations. Constructed for durability, efficiency, and space-saving operation, dual plate check valves are the priority in modern-day industrial pipeline systems. 

 What is Dual Plate Check Valve? 

Double-door check valve or a double plate check valve is a non-return valve employed to prevent backflow in pipes. It is comprised of two hinged-in-the-middle spring-loaded plates that open up when the flow is in the forward direction and shut up when the flow is in the reverse direction. 

 Why Required? 

Backflow can destroy equipment and fouled fluids. Dual plate check valves offer a compact, light solution to prevent reverse flow, ensuring process integrity, safety, and compliance in oil and gas, power, and water treatment applications. 

 Key Components of Dual Plate Check Valve 

• Valve Body: Typically constructed of stainless steel, carbon steel, or ductile iron. 

• Dual Plates/Discs: Part away when flow passes and seal when it stops or reverses direction. 

• Hinge Pin: Facilitates the plates’ movement. 

• Spring Mechanism: Prevents backflow by ensuring rapid closure. 

• Seat: Closes and forms a seal around plates. 

 Working 

When flow is in the desired direction, pressure opens the plates, allowing passage. When flow reduces or reverses, the torsion springs snap the plates shut to prevent backflow. Rapid closure prevents water hammer, a common pipeline issue. 

 Advantages of Dual Plate Check Valve 

• Compact and light design
