Pressure Retaining Valve – Overview The V86 Pressure Retaining Valve works to keep the pressure at the valve inlet constant at all times, ensuring problem-free operation of the system as a whole. It is made for pipes of larger dimensions. The V86 pressure retaining valve serves to keep the working or system-related pressures constant, to balance out pressure pulsation and to reduce pressure peaks in chemical process systems. If the inlet pressure rises above the set value, the pressurised valve piston is lifted against the spring resistance. As a result, the valve opens and the pressure in the outlet pipe is reduced. The valve closes as soon as the inlet pressure sinks below the pre-set spring tension. For neutral and aggressive media with a small number of particles or solids. The chemical resistance depends on the selected valve material. Pressure Retaining Valve – Features No auxiliary energy required The working pressure is set with an adjusting screw and locked with a locking nut Valves can also be adjusted under working pressure Minimal maintenance and can be installed in any position All parts in contact with medium made of highly resistant plastics Large form of the housing allows good flow values
