Design Features

Containment of Dangerous Emissions
All valves are fitted with a UNS N10276 bellows seal guaranteed for 20,000 Open/Close/Open cycles. Valves are also designed with back up secondary pure PTFE packing glands and seals as standard.
Repeatable tight closure and isolation.
For metal to metal seated valves the disc is harder than the seat minimising disc damage during operation ensuring long life for the seating surfaces.
Polymer ring soft seat plugs are also available.
Open Bellows Design
Our design of open bellows and bolted top assembly gives easy access to inspect the bellows assembly area. The open design ensures that any corrosion products in the fluid do not get trapped around the bellows causing damage and early failure.
