MB-2.5DT Compact
2-Way 5-Valve Transmitter Direct Coupling Manifold
Working Pressures 100 | 420 bar (1500 | 6000 PSI)

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.

Tests

According to API STANDARD 598, each manifold is tested to check the leakage in the seat and packing. Under request, the corresponding materials and test certificates can be delivered with the manifold.


   Packaging

All TECVAL manifolds are supplied packed in individual polyethilene airtight bags, which include the general features of the manifold. End screw connections are protected with polyethilene caps. Everything is 100% recyclable.
Maintenance

Adjustment of the packings may be necessary during the working life of the manifold. The operation consists of turning the glands (12) clockwise.
Manifolds with long no-working period may have a harder initial operating torque.
