MB-1.2
1-Way 2-Valve Manifold
Working Pressures: 100 | 420 bar (1500 | 6000 PSI)

TECVAL MB-1.2 manifolds are designed to work with fluid under high pressure and/or high temperature service. Their distribution diagram consists of two valves commanding the main line, where inlet and outlet are at 180º, and a discharge line outlet at 90º outflow. This purge line can be 1/2" or 1/4".

Tests

100% tested according to API STANDARD 598. Each manifold is tested to check the leakage in the seats and packings. Under request, the corresponding materials and test certificates can be delivered with the manifold.


Packaging

All TECVAL manifold are supplied packed in individual polyethilene airtight bags. 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 nuts (3) clockwise.
Manifolds with long no-working period may have a harder initial operating torque.
