Blower Protection
Controlled excess-pressure relief helps protect the blower when operating pressure rises above the nominal value.
RV SERIES · BLOWER ACCESSORIES
Plastic Relief Valves
RV Series plastic relief valves are installed on the inlet or outlet of side-channel blowers. They regulate blower operating pressure and protect the system against excessive pressure. When the operating pressure exceeds the nominal value, the valve relieves excess pressure and helps protect the blower.
