All data are considered to be unbinding reference values. We accept no liability for data selection that is not confirmed in writing. Pressure data refer, if not otherwise indicated, to liquids of Group II at +20°C. 6 Pressure gauges - accessories Application: Pressure gauge pushbutton valves are used for spot pressure measurement. If the cock is not operated the pressure gauge remains unpressurised. When the pushbutton is depressed the pressure gauge is set under pressure and the system pressure is displayed. On releasing the button, the system is automatically disconnected and the pressure in the pres- sure gauge is released into the atmosphere. Temperature range: -20° C to max. +60° C MAH 12 DK G 1 / 2 “ * gas max. PN 4 bar Pressure gauge pushbutton valves with DVGW approval PN 25* Application: Pressure gauge shut-off valves are installed to protect pressure gauges. The fulfil a double function,dam- ping of pressure thrusts through flow control direction, and they also isolate the pressure gauge from the pressure line. The rotatable union nut permits the pressure gauge to be positioned in the desired direction. The inserted O-ring seal is included in delivery. There is no pressure relief of the pressure gauge.

The lever can be switched to "Continuous" - pressure is applied to the measuring device, "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.

Setting the valve to throttle can cushion spikes in pressure and vibrations, and separate the measuring device from the supply line completely. A bleed screw can be used to release pressure from the gauge. Otherwise, no pressure is re- leased from the gauge while the valve is closed. For low pressures and non-aggressive substances, we recommend using pressure gauge stop cocks.
