Water system pressure relief valve DHV718

PVCPTFEdiaphragm

• For constant work pressures • Low vibration, control of pressure peaks • Easy adjustment of pressure, also during when working • 100% free return pressure in the rest position • PVC, PP and PVDF materials • PTFE membrane Advantage • Stable regulation behavior and reduced vibrations • Requires little maintenance • Low pressure increase until full valve opening • Components free of friction • Absolutely watertight by flat membrane with cameras • For viscous fluids and solids content • ATEX Authorization Applications • Construction of chemical facilities • Construction of industrial facilities • Water treatment • Galvanotécnica Use • Directly controlled by the fluid, the pressure maintenance valve serves in the industrial plants for the stabilization by the primary side of the working pressures preset • To avoid pressure spikes, the pressure maintenance valve can also be used as a discharge valve. The pressure holding valve is mounted for this on a bypass line.
