- Reduced leakage can be obtained with our Step Seat valves on limited applications, high and low temperature gasses
- Sizes from 2in (50mm) up to 88in (2200mm)
- Streamlined shape disc which provides minimum resistance to flow and on larger valves ribs are incorporated for extra strength
- Standard pattern valves are generally designed to suit a static maximum pressure up to 10 bar and pressure differentials depending on valve size and construction
- Temperature ranges of up to -190°C up to 1000°C
Benefits
- Low torque
