TESCOM™ Anderson Greenwood Instrumentation Model M3A Differential Pressure Manifolds
A compact manifold incorporating a PTFE-packed valve.
This single valve serves to equalize a differential pressure transmitter at pressures up to 6000 psig (414 barg)


  • Reduced installation costs of up to 20%-30% by manifolding the instrument, eliminating several components essential for ‘piping-up.’
  • Compact design requires minimum space for operation and installation.
  • Reduced leakage through fewer parts to assemble.
  • Free-swivelling ball end stem provides repetitive bubble-tight, metal-to-metal valve closure.
  • Adjustable stem packing results in long, leak-proof service.
  • Packing below stem threads prevents galling and thread corrosion.
  • Integral hard back seat protects against stem blowout.
  • Rolled stem threads provide a stronger, more durable thread area, increasing valve life.
  • Two PTFE or graphite gaskets, 4 x 7/16” and 20 x 2½” zinc cobalt plated alloy steel bolts supplied for mounting as standard.
