The HM20 Instrument is designed exclusively for single, remote mounted pressure transmitter, switch or gauge installations. In the past, these instruments were often mounted on conventional valve and fitting assemblies with gate, globe, or ball valves, and offered minimal instrument support with high risk of fugitive emissions.

The HM20 Series manifold combines shutoff and bleed functions, along with calibration access into one compact, well supported unit that can be mounted on a 2" pipe stand. Emissions are reduced because all valves are integral to the barstock body, thereby eliminating externally threaded bleed valves as supplied on other manifold designs.
