Testing, Testing, 1 - 2 & 3 The A-T Houston facility has recently added state-of-the-art valve testing equipment for our Trunnion product line.

The equipment includes two testers that can handle 2"-12" valves, with a test pressure up to Class 2500 or a shell test pressure of 9,375 psi. The large 14"-36" tester can handle large diameter ball valves up to Class 1500 or a shell test pressure of 5,625psi.
These testers meet the most stringent valve testing requirements of API 6D, ASME B16.34, ISO 5208 and many other industry standards. Testing capabilities include hydrostatic seat test, shell test, double-block-and-bleed test, double-piston-effect seat test as well as low-pressure pneumatic air test.

Unlike other conventional hydraulic type testers, these testers do not apply an excessive external clamping force to the valve ends that could affect the seat leakage test results.
The testers utilize a unique piston effect design on the end flange which applies just enough sealing force during testing. All testers are equipped with a touch screen control panel and the pressure test results can be monitored and recorded in real-time. Every trunnion mounted ball valve is fully tested per API 6D requirements before shipping to the customer.
