GF Piping Systems
The pressure retaining valves V786 and V186/V86 from GF Piping Systems serve 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 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.
