Valves - Reduce Emissions and Save

Protect environment (meet legislation requirements) but also reduce cost due to loss of medium in processes.

In addition to the function -which also includes internal tightness-, external tightness plays a central role in valves under the specified regulatory boundary conditions. This means that -depending on the design- e.g. the valve stem seal and the cover seal come into focus.

AMTEC offers the complete chain of products and services:

We make the selection of suitable gaskets and packings easier for you with data from our test laboratories.
AMTEC has the appropriate testing facilities for testing sealing elements such as stuffing box packings and flat gaskets and can use many years of experience.
We prove the high quality of the seals used in the valves.
For this purpose, we have developed test rigs that cover a wide range of applications (valve types and loads).
With the correct assembly of your tightening connections, you reduce emissions and increase the availability of your systems.
Last but not least, based on our practice in nuclear power plants, we are specialists in the controlled, reproducible
assembly of packings and seals.

With this background, we are of course the first address for

leak detection and repair (LDAR).

Testing of Packings and Valves in the Laboratory

Valve tightness and function base essentially on knowledge of the characteristic properties of a stuffing box packing and on a correct installation. With our packing test rigs we measure compression and deformation characteristics and coefficients of friction. Specific assembly and measuring equipment ensure that the required preload is maintained within narrow tolerances.

Our valve test rig provides type tests of valves including mechanical load changes (spindle, internal pressure) and thermal load changes. The valve stem forces and the leakages at the stuffing box packing, cover and seat are measured. This enables realistic functional tests under representative operating loads, e.g. for product development tests.

Our experience in testing seals and stuffing box packings as well as testing of valves is available in our testing laboratories
