Three Valve Manifolds  - PG45 Series

PB/PG 45/46/53/54/51 Series Three Valve Manifolds


Hex Valve produces a complete line of three valve instrument manifolds which combines two block valves and one equalizing valve in a single compact assembly.

PG45/46 Series: for in-line, thread by thread installations
PB53 Series: single flanged for mounting to a remotely located differential pressure transmitter
PB54 Series: double flanged for direct mounting to the orifice flange or for remote transmitter locations
PB51 Series: direct mounted compact wafer valve


  • 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.
