TECVAL foto731478260641

TECVAL MBT-2.3DT manifolds are designed to work with fluids under high pressure and/or high temperature service. Their distribution diagram consists of three valves commanding three lines: high pressure, low pressure and a by-pass line to restart the instrument. The coupling is manufactured according to DIN EN 61518. Four screws 7/16” UNF and two PTFE joints to assemble the transmitter are supplied.


  • High-strength forged body.
