Pressure reliefvalve

Hydraulic valve damper and progressive flow opening minimise ‘hunting’ flow modulation problems over a wide flow and head pressure range.

Well designed steam systems produce clean dry steam for delivery at high pressure - the best quality steam at the lowest cost.

Effective control demands an automatic valve that can reduce steam pressure accurately, reliably and at a cost to suit the application.

Providing anti-syphon protection, the valve is capable of flow rates of up to 180 litres per minute. The diaphragm servo assisted operating method allows high flow and low vacuum pressure loading of the dispenser pump – unlike spring resistance type designs.
