Testing facilities
To ensure that our customers receive the best possible product quality, each completed valve passes through our test facility. The test facility is completely computer-controlled and re-checks all the configuration data relevant for the customer, for example:
- Operating volume
- Delivery height
- Differential pressure
- Opening/closing points
