Differential Pressure Manifolds

KM4A & KM4T 3-Valve

Product Brief

The KM4 style 3-valve manifold is designed for either direct (4A) or remote (4T) mounting to differential pressure transmitters with 2-1/8 inch (54 mm) centers. It contains two (2) main block valves plus an equalizing valve.

Features/Benefits

  • Bubble-tight shutoff. Every valve 100% tested.
  • Space-saving design. One valve replaces three. Less parts equals less leaks, equals less fugitive emissions.
  • Roddable design of soft seat valves often eliminates purge-style cleaning, simplifying maintenance.
  • Blowout-proof stem. Stem design prevents accidental back-out, eliminates blowout problems.
  • Rolled stem and bonnet threads increase strength, wear resistance and life.
  • Highly polished stems yield easier operation and increased packing life.
  • Metal-to-metal bonnet-to-body seal maintains pressure integrity, eliminates bonnet thread process corrosion, and ensures a reliable seal.
  • Stem threads isolated from the process fluid. Packing adjustment below the threads prevents thread corrosion.
  • Multiple packing options available including Teflon® and GRAFOIL® packing.
  • Bonnet cap protects stem threads from atmospheric corrosion, increases valve life.
  • Direct pipestand mounting to 2-inch pipe. Requires KMC Mounting Kit. Permits complete piping installation without the transmitter and simplified instrument removal.
  • Soft seat is field-replaceable with valve in line. Metal seats also available.
