A range of 2, 3 or 5-valve integral manifolds for connection to bottom inlet, low-profile pressure transmitters


  • Ball end stems eliminate seat galling, provide bubble-tight shutoff and long life. Hardened, non-rotating balls ensure perfectly aligned closure.
  • Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
  • Easily adjustable PTFE packing decreases replacement downtime and increases valve life.
  • Dust covers protect stems from lubricant contamination.
  • Safety back seating prevents stem blowout or accidental removal and provides a metal-to-metal secondary stem seal while in the fully open position.
  • ENC plated 316 SS stems prevent galling or freezing of stem threads.
  • Rolled stem and bonnet threads provide additional strength.
  • Mirror stem finish in the packing areas provides smooth operation and extends packing life.
  • Metal-to-metal body-to-bonnet seals in constant compression prevent bonnet thread corrosion, eliminate possible tensile breakage and give reliable seal points.
  • Bonnet lock pins prevent accidental separation from the body while enabling easy maintenance and repair.
  • Manifold transmitter installation envelope same as Coplanar installation.
