Assembly/
Commissioning
We help you with the commissioning and installation of your valve – worldwide!
INSPECTION
Our valves do not leave our premises without first being “checked out”. On our modern test benches we offer tests according to API 598, EN12266-1 and -2, ANSI FCI 70-2, ISO 5208 and also other customer specific requirements. On request also with chart recorder monitoring.
We perform leakage tests with the following test media:
- water
- air
- nitrogen
- helium
Furthermore, the following tests can be conducted by us on request:
- Helium test according to SPE77/312 class B or customer requirement
- Cryotest according to BS6364 or customer requirement
- Emission tests according to ISO 15848-2
- PMI test
- NDE tests (X-ray, ultrasonic, dye penetrant and magnetic particle inspection)
Our test stand is equipped with automated bubble and drop counter.
Replacement
of
fittings
Over time, the requirements for a valve may change. We check with you whether the valves already installed still fit the design parameters or whether the valves should be replaced.
Our
Spare parts
We document every valve we manufacture. Therefore, even after years, we can still trace back the components from which your valve was manufactured and, based on this information, offer you the appropriate spare parts. Of course, we have a large quantity of spare parts in our stock and can therefore offer you a short delivery time.

Check-Up/ Inspection
Is the valve leaking? The actuator does not do what it should? If there are problems with our products, we will send an experienced technician to you to find a solution as quickly as possible.
Maintenance/ repair
We do not use external companies. Our in-house mechanics know our products very well and repair them directly on site! If this should not be possible, then we repair your valve also with us in the house.
