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.

With this background, we are of course the first address for
Valve tightness and function base 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 experience in testing seals and stuffing box packings is available in our accredited testing laboratory, e.g. for product development tests of
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.
In our valve test rigs, we demonstrate the high quality of the seals installed in valves. The tests are carried out according to e.g.
Another important step towards a reproducibly functional and tight valve is a controlled assembly of the sealing connections, here in particular the
