Pressure-reducing valve DV750

diaphragmmanualadjustment

• Control valve for pressure reduction • We obtain constant work pressures • Low vibration and behavior control • PVC, PP and PVDF materials • PTFE membrane, EPDM or FPM gaskets Advantage • Valve adjustment also under working pressure • Absolutely watertight by the valve membrane • High operating safety and long service life • Secure membrane clamping with stainless steel screws in series • Reduction of the pressure by throttling in the valve seat • In series with two lateral screw connections for the pressure gauge or membrane separator Applications • Construction of chemical facilities • Construction of industrial facilities • Water treatment Use • For the reduction of system pressures at almost constant working pressures Function of the valve • The open valve is balanced between the inlet pressure (primary pressure) and the lowest working pressure (secondary pressure). If the working pressure increases above or falls below the desired value, the large surface membrane is pressed up or down against the spring. The valve starts to close or open until the equilibrium state is reached again, that is, regardless of whether the inlet pressure increases or decreases, the working pressure remains constant (if the inlet pressure> working pressure).
