3 WAY DIRECT MOUNT VALVE
(TYPE 1)

The 3-Way Direct Mount Valve (Type 1) is a precision instrument valve designed for direct mounting onto pressure transmitters or differential pressure instruments. This valve enables users to isolate, equalize, and calibrate without disconnecting the instrument from the process, making it essential in pressure measurement and control systems. This valve is typically used in refineries, chemical plants, offshore platforms, power plants, and process industries, offering reliable and compact valve functionality directly at the instrument site.

  • Direct Mounting Design: Bolt directly to DP transmitters (e.g., Rosemount, Yokogawa, ABB), Standard 54mm or 2-1/8″ center-to-center dimension
  • 3-Way Functionality: 2 x Isolation Valves (High & Low sides), 1 x Equalizing Valve
  • End Connections: Process: 1/2″ NPT Female (or customized), Instrument: Flanged (direct mounting)
  • Bonnet Style: Integral or screwed bonnet
  • Stem Tip: Non-rotating or soft-seat options
  • Vent/Drain Ports: Optional for pressure release
  • Pressure Rating: Up to 6,000 psi (414 bar)
  • Temperature Range: PTFE packing: Up to 232°C, Graphite packing: Up to 425°C
  • Body Materials: SS316, SS304, Monel, Hastelloy, Carbon Steel, Duplex
  • Simplifies installation by directly connecting to transmitters—no impulse tubing needed.
  • Reduces leak paths and enhances system integrity.
  • Allows zeroing and calibration of DP transmitters without disconnecting.
  • Compact and rugged design reduces space requirements and withstands harsh environments.
  • Ensures safe isolation and equalization with minimal downtime.
  • Compatible with major transmitter brands and complies with international standards.
