TESCOM™ Anderson Greenwood Instrumentation Model PTM/PT7 Differential Pressure Manifolds
PTMPT7 Differential Pressure Manifolds
Two valve calibration manifolds with a choice of metal and soft seats for static pressures up to 6000 psig (414 barg)


  • Cost savings of 20-30% when manifolding instruments by eliminating several parts used in conventional methods of ‘piping up’.
  • Compact design requires minimum space for operation and installation.
  • Shutoff valve, tee, calibration valve and all immediate tubing/fittings available in one simple manifold.
  • PTM’s unique valve seat can be converted from soft to hard simply by removing two insert washers.
  • Stem and bonnet threads are rolled for increased strength, preventing galling and adding years to the useful life of the valve.
  • Fewer leak points reduce leakage by having fewer parts to assemble.
  • PTFE and graphite adjustable packing is easily adjusted for leak-proof, long service life.
  • PTM’s O-ring stem seal stem design isolates the stem threads from the process, preventing galling and corrosion.
  • Back seat stem prevents blowout.
