Ordering information

References are formed by three parts:

Manifold Code Look for it in the order codes chart on the previous page.	..	Option/s -If required, add the code/s from the options section on the previous page (in alphabetical order)	...	Material -Look for the code on the materials chart.
An example of manifold and two options: Manifold MBT-2.3 1/2"NPT AISI-316L with movable stem tip and two outflow bleed screws of : 3100 FP A4 The reference to place the order is 3100FPA4.

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 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.
