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.
