Check valve are Primarily Single Plate Swing Check Valves with a Short Pattern Wafer Body Conforming to the API6D and ASME B16.10 Face to Face Dimensions. The Valve has a Simple but Reliable and Robust Construction. The low Inertia Disc Design Enables the Valve to Open or Close with a vary low Differential Pressure Which Makes them Ideal for Services Operating Under low Differential Pressures.
The Valves Is Ideal for Pump Discharge Duties. The Eccentric Mounted Hinge Pin In Combination with the Disc Seat Guarantees a Positive Shut off of the Returning Media.

- Very simple in construction, compact, lightweight sturdy & rugged.
- Soft seated valves come in two variants – 0 ring seated and PTFE / RPTFE seated.
- Wafer-type end connections as standard – other types can be provided on request.
- Long life and trouble-free operation.
- Double-offset butterfly valves also cool air, water, and gases. They can also compress air or gas applications and control/isolate flow. In some situations, the valves can stop backflow from occurring.
- Both gas pipelines and remote offshore oil rigs operate in extreme conditions. So, they require durable valves like double-offset valves to hold up against harsh environments and refinery media.
The valves help reduce maintenance task and add longevity to different systems. Butterfly valves are very rugged and often designed to meet specific uses. - Some industries use double offset butterfly valves as a standard shut-off valve. That’s because they offer a much tighter seal than globe and gate valves.
- When using at the dead end of pipeline, reverse preferential flow direction.
