Quality Control
Each manufacturing step is subjected to the quality control review to insure the accuracy of the valves dimensions with respect to the drawings.
Each valve must pass two types of test:
1-Air leakage test, which tests the seats performance 2-Shell thickness test (Hydraulic test), which tests the valve body to ensure that it, can withstand its nominal pressure.
Warehouse
The stock strategy is to provide a 100 % of the components and valve bodies of all the production lines to be able to continually feed the workshops. On shelf products stock to minimize delivery time.
