All of our pressure tests and material checks are witnessed
by an inspector who signs off on their accuracy. A laminated card
is then attached to the valve with each test and material check
indicated, as ceritification to our customer that these procedures
have been followed. Every valve comes with this certification
attached to it.
Eevery valve is tested.
We test 100% of our valves with water or kerosene. the water
is mixed with suitable inhibitor to prevent corrosion.
We test our valves at extended time periods to further assure
the quality of the valve performance. In addition, we test our
valves with air at 0.8MPa to insure the casting integrity.
