In-Line Three Valve Manifold with Vent - HM46 Series

HM46 Series In-Line Three Valve Manifold with Vent


The HM46 Series is the same design as the HM45, but also incorporating a vent valve allowing a technician to perform instrument bleed or blowdown procedures. Both models provide one compact valve assembly to perform the block and equalizing functions required to calibrate your instruments. They feature backseated, inside rising stem construction to prevent accidental stem removal and to isolate the packing from the process. For added protection, the bonnets are pinned to prevent inadvertent removal.


  • Non-Rotating Tip (NRT) Stem - Provides tight, repeatable shutoff without the galling or cross-scoring that occurs on ball type stems.
  • Minimum Emission Flange - Outlet flange face protrusion mates transmitter inlet cavity, providing a gasket ID barrier that offers maximum protections against gasket cold flow and fugitive emissions.
  • Removable Bracket Option - Specify our removable bracket option and mount the manifold, not the transmitter.
