The Type9 Pressure Sustaining / Surplus Valves are designed to sustain and control the upstream pressure and pass surplus mediums into a zone where they can perform useful work or be recovered and conserved. The type 9 has a piston and lid of equal diameter, making the two areas balanced. This makes the valve suitable for applications where variable back pressures are present. The valves are supplied in sizes ½” to 6” and can be manufactured in Gunmetal, Cast Steel and Stainless Steel with ends screwed female BSP or flanged ends to customers’ requirement. The standard set pressure range of type 9 is 0.70 Bar g, although higher and lower set pressures can be accommodated

Sizes available: ½” – 6”
