Pressure Relief Valves
Can be set to a pressure and open automatically when exceeded. When valves on pumps, dividers or branchpipes are opened or closed too abruptly, as well as through excessively fast water input, pressure shocks (water hammers) occur in the hoseline. These may amount to several times the operating pressure and damage hoses, pumps and fittings. Pressure relief valves absorb these pressure shocks quickly and safely.
Technical Information
Pressure relief valves hydraulically operated with gauge
3300As a rule, it is installed upstream of the divider and set to the required operating pressure between 2 and 16 bar at the illuminated pressure gauge. The reaction time is 0,1 sec. at 0,5 bar above the pressure setting.
