Application:
Pressure gauge stop cocks are used to protect pressure gauges against spikes in pressure and vibrations.The lever can be switched to “Continuous” - pressure is applied to the gauge, “Shut-off” - pressure gauge is separated from the supply line but the pressure is not released, or “Shut-off with draining” - pressure gauge is separated from the supply line and pressure is released into the atmosphere from the space between the cock and the pressure gauge. For high pressures or aggressive substances, we recommend using pressure gauge shut-off valves.
