BELLOWS SEAL TYPE 2-WAY & 3-WAY GLOBE VALVE
Wasted material, employee safety, environmental concerns all good reasons for today’s plant operator to be concerned about fugitive emissions from hazardous processes.
To stop packing leakage from control valves.
Using a formed a formed metal bellows design with minimal welded joint, the design of PROVAL bellows has a full-cycles lift up to 5 a hundred thousands cycles.
This ensures years of safe and reliable operation in hazardous process ranging from -160°C(-230°F) ~ 350°C (688°F) and pressure to 40(kgf/cm²).
A metal should envelopes the bellows acting as a pressure boundary in service, allowing use of a single, pressurized gasket seal and preventing fluid contact with the bellows housing during normal operation.
