SHUT-OFF VALVES
DESIGN FEATURES
- Lightweight and economical valve in relation to its size due to special welded construction and adaptation to operating conditions.
- Seat welded onto the body and disc, made of corrosion- or erosion-resistant chromium-nickel steel.
- Very low breakaway torque, 45% lower than with laminated sealing rings.
- Gas-tight seal with any valve installation position due to special dimensioning and shaping of the body seat and disc.
- The valve stem is sealed from the medium chamber to the atmosphere with an adjustable packing, the material of which is adapted to the operating conditions.
- Standard actuator for on-off function is a pneumatic piston actuator, double-acting.
