Hydraulic Pressure Gauge Assemblies

We have two different pressure gauge assemblies designed for the processing industry. Installing only a pressure gauge and leaving it exposed to pressure constantly will wear it out very quickly. It is desirable to have some type of gauge isolator so that the bourdon tube in the gauge is only exposed to pressure when you actually want to read the gauge.

The gauge assembly on the left is a push-to-read type of gauge isolator. It is actually a 3-way valve, so when you push the button, you are able to read the pressure. When you release the button, this trapped pressure is returned to the tank, keeping the gauge exposed to zero pressure except when being read. It comes with the bracket ready to bolt or weld, and fittings that are -4 male JIC. Any fittings can be pre-installed to meet your application. Not included are the two hose assemblies to connect to the pressure and the tank ports.

The gauge assembly on the right connects directly into the pressure port of a pump, shown connected to a Continental PVR50-70 vane pump. It has a needle valve to isolate the pressure from the gauge except when reading the pressure. In this style, pressure can be trapped in the gauge after the reading is taken and the valve is closed.

Both of these gauge isolator assemblies are rated for 3000 psi, and are available with a 2000 or 3000 psi gauge installed as shown. The push-to-read gauge isolator on the left is available with a double bracket that will hold two gauge isolator assemblies.
