SUPER DUPLEX CHECK VALVE MANUFACTURERS IN INDIA

Speciality Valve is one of the leading Super duplex check valve manufacturers in India by the top name for supplying tough and corrosion-resistant check valves to deal with the toughest of industrial applications. Our check valves are made of premium super duplex stainless steel to offer longer life and better performance under heavy-duty operations.

Check valves are required to avoid backflow in piping systems to protect pumps and other vital components from damage. For corrosive chemicals, high salinity, or high pressure, super duplex material is required due to its high mechanical strength coupled with corrosion resistance.

Key Components of Super Duplex Check Valve:

1) Body: Made of super duplex stainless steel to provide maximum corrosion resistance.
2) Disc/Clapper: The component that can move to open or close based on flow direction.
3) Hinge or Spring Mechanism: Allows for movement of disc as per valve design.
4) Seat: Gives a leak-free seal against backflow.
5) End Connections: Flanged, threaded, or welded ends based on application requirements.

Working of Super Duplex Check Valve:

A super duplex check valve works automatically without control from outside. The flow in the intended direction raises the disc away from the seat, allowing the flow. For the reverse flow, the disc rests on the seat, stopping the reverse flow. Use of super duplex provides good operation in high-pressure and corrosive systems.

Benefits of Super Duplex Check Valve:

1) Acceptable resistance to corrosion in chloride-environment and acid atmospheres
2) High strength-to-weight ratio
3) Low maintenance and extended service life
4) Avoids reverse flow and system damage
5) Ideal for vertical and horizontal mounting

Functions of Super Duplex Check Valve:

1) Preventing backflow
2) Pressure maintenance
3) Pump and compressor protection
4) For ensuring unidirectional flow
