Shut-off valve test bench S-4-300/40

pressurefully-automaticsafety valve

Test bench for shut off valves DN 10...300 mm (2...12″) PURPOSE • shell test acc. to API 598, API 6D, ISO 5208 etc.; • seat leakage test (cavities A to B, B to A) acc. to API 598, API 6D, ISO 5208 etc.; • backseat test acc. to API 598, API 6D, ISO 5208 etc.; • DBB/DIB test acc. to API 598, API 6D; • control valve seat leakage test, acc. to ANSI FCI 70.2, IEC 60534-4, EN 1349 etc. TESTED ITEMS • gate valves; • ball valves; • globe valves; • check valves; • butterfly gates; • plug valves. ADVANTAGES ■ Clamping of tested valve provided by hydraulic cylinder, optionally test bench can be equipped with proportional clamping control system, which excluding axial compression applied to the valve body during clamping by hydraulic cylinder, during high pressure testing.* ■ The two-sided gate sealing during tests do not require the tested valve rearrangement, which significantly reduces the test time. ■ The test preparation time is significantly reduced by using the high-pressure fast coupling hoses. ■ The bench is quickly adjusted to face-to-face dimensions of valve by using the electrically driven cross-head. ■ The patented design of the self-sealing adapters exclude axial compression during the tests, which ensures the test reliability, protects the valves against deformation, and extends the valve life.* ■ All water-wetted parts are corrosion-proof. ■ The bench can be equipped with replaceable sealing adapters.* ■ Increased-diameter hoses reduce the time of the valve filling with the test medium. ■ The tested valve clamping technique is used to ensure visual control of leakage points. * Upon customer request.
