Double & Single Seated Control Valve

This series covers a wide range of general process applications on air, water, steam, oil, gases and chemical services where dead tight shut-off is not essential. It is particularly useful for throttling duty at relatively high pressure drop, or when high capacity is required. Leakage when shut is less than 0.1% (Class III) of maximum capacity with standard design. Leakage Class IV with 0.01% of maximum flow capacity is also available with stellite trims. Class VI option is also available with PTFE soft seat on the plugs, on request.
