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 nuts (3) clockwise.
Manifolds with long no-working period may have a harder initial operating torque.
