5-клапанный коллектор с дистанционным монтажом, модель HM8532 | Remote Mount 5-Valves Manifolds | HM853211F8YL

Using the 5-valve manifold
In normal operation the “isolate” valves are open while the “equalize” and “vent” valves are closed. This provides a differential pressure reading to the pressure gauge or transmitter.
To zero the instrument, first close both “vent” valves and the downstream “isolate” valve. Then open the “equalize” valve and adjust the zero setting on the instrument.
To remove the instrument, first close both “isolate” valves, then open the “equalize” valves to relieve pressure
