Pressure Relief Valve DHV 712-R

The DHV 712-R maintains the upstream pressure at a set value to protect the piping in case of override pressure. The thrust of the pressure of fluid on the diaphragm must be greater than the spring strength to release the fluid by the outlet. The diaphragm in EPDM (PTFE coated) separates the adjustment dry space (including the calibrated spring), from the lower space for flowing fluid. All wet parts are made of plastics; The adjustment screw is protected with a plastic cap and secured by a lock nut.
