Over-/under pressure safety valves
Over-/Under-Pressure Relief Valve is a safety device designed to protect biogas reactors, tanks and gas holders against excessive pressure and vacuum. Reliable sealing is achieved using a liquid seal, typically a water-glycol mixture, with density determined by the mixing ratio. The valve provides safe and stable operation of biogas installations and features a robust, low-maintenance design. Available sizes: DN150, DN200 and DN300.
over- and under-pressure safety relief valve designed for biogas tanks, digesters and gas storage systems. The liquid-sealed valve protects tanks and gas storage membranes against excessive pressure and vacuum. Made of V4A stainless steel (1.4571), it features a DN 200 PN10 connection and provides a blow-off capacity of up to 1,250 m³/h and an air intake capacity of up to 750 m³/h
