Pressure/Vacuum Relief Valves

Pressure/vacuum relief valves are specifically designed for tank protection, and are used extensively on anaerobic digesters and gasholders to prevent the build up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel. The range includes pressure only, vacuum only and combined pressure/vacuum valves, all available with flanged outlets or vented to atmosphere. Pressure relief valves supplied by PROGECO can be fitted with integrated flame arrester, and are ATEX certified.
