Reference Standards:

TSGZF001-2006, GB-T12242-2005, GB-T12241-2005, GB-T12243-2005

Range of application: applicable for the set-pressure, setback pressure and sealing tests of direst loaded and pilot-operated safety valves.

Technical Parameters:

•         Maximum drift diameter: DN400mm

•         Maximum test pressure: 60Mpa

•         Pressure test precision: pressure gauge of 0.4 grades (Users can choose a more precise one.)

•         Test medium: nitrogen, compressed air or clean water (Gas liquid dual-capable one can be designed.)

Functions and Characteristics:

•         The equipment has advanced design principle. It uses pneumo-hydraulic booster pump as its clamping pressure source and air driven gas booster pump as its test pressure source. A gas cylinder is equipped, which enables the test to be conducted continuously.

•         The test pressure is adjustable and the process of pressurization is stable.

•         Clamping pressure source and test pressure source can use imported booster pumps from America or Germany, which have a wide range of output pressure.

•         All the manual high pressure valves, pipe fittings and connectors are imported ones, which guarantee their pressure levels, safety and reliability. Most gas and liquid media are available.
