TECVAL MB-2.5DT Compact manifolds are designed to work with fluids under high pressure and/or high-temperature service. All its stem threads are isolated from fluid. Their distribution diagram consists of five valves commanding two different pressure lines: high pressure, low pressure, and a by-pass line to restart the instrument. The coupling is manufactured according to EN 61518. Four screws 7/16” UNF and two PTFE joints to assemble the transmitter are supplied.

Features

  • Metal-to-metal shut-off.
  • Stem threads are isolated from fluid.
  • Movable stem tip.
  • Easy external packing adjustment.
  • PTFE packing.
  • 100% tested.

Options

  • Grafoil packing for high temperatures.
  • High working pressure 420 bar (6000 PSI).
  • Four screws M10 instead of 7/16" UNF.
