Pojistné ventily

The pressure relief valves V185 and V85 serve to keep the working or system-related pressures constant, to balance out pressure pulsation and to reduce pressure peaks in process systems.

The third pipe spigot fitted on the valve body means the valve can be installed directly in the main pipeline.

If the inlet pressure rises above the set value, the pressurized valve piston is lifted against the spring force. Consequently, the valve opens and there is a reduction of pressure in the outlet pipe. The valve closes as soon as the inlet pressure sinks below the pre-set spring tension.
