Pressure Regulating Valve
V82 Pressure Reducing Valve
The V82 Pressure Reducing Valve reduces the pressure within the system to a pre-set value. By using the differential pressure, the pressure reducing valve adjusts itself to the set working pressure. The outlet pressure (working pressure) is not directly related to the inlet pressure. If the outlet pressure increases or decreases above/below the desired value, the diaphragm is lifted against the spring force or pressed down by the spring force, as the case may be, by the outlet pressure. The pressure reducing valve begins to close/open until a state of equilibrium is re-established, in other words, the outlet pressure remains constant irrespective of an increasing or decreasing inlet pressure.
The wide range of materials available for the housings (PVC-U, PP, PVDF) and the diaphragms (EPDM, EPDM-PTFE-coated) cover many areas of application for technically pure, neutral and aggressive fluids as well as ultrapure water applications.
General:
- Valve housing: PVC-U, PP, PVDF
- Diaphragm: EPDM, EPDM-PTFE-coated
- Pressure ranges: DN65 - DN80; 0.5-6 bar DN100; 0.5-4 bar
- Hysteresis: approx. 0.4 to 1.0 bar
- Pressure difference between inlet and outlet : 1 bar
Features:
• All parts in contact with the medium are made of highly resistant plastics.
• The actuator is separated and hermetically sealed off from the fl ow section by the control diaphragm.
• The working pressure is set with an adjusting screw and locked with a locknut.
• The large control surface and the disc spring keep standard tolerances small.
• No auxiliary energy is required to operate the valve.
• The valve is largely maintenance-free and can be installed in any position.
• Valve can also be adjusted under working pressure.
• Standard version with manometer.
