Item description
Application:
Pressure gauge shut-off valves are used to protect pressure gauges against spikes in pressure and vibrations. Setting the valve to throttle can cushion spikes in pressure and vibrations, and separate the gauge from the supply line completely. A bleed screw can be used to release pressure from the gauge. Otherwise, no pressure is released from the gauge while the valve is closed. For low pressures and non-aggressive substances, we recommend using pressure gauge stop cocks.
