1.JWT-valve test bench Technical performance and feature

● It's mostly suitable for the welding valve and as well as uses to flange and thread valve extra-high pressure under the condition

of matching with the plane seal plate, high and middle pressure performance test, adopts the hydraulic oil cylinder tip press method to

carry out the clamp operation, fully meet the GB/T 13927-2008, JB/T 9092-99, the API 598 requirements.

● The system equips with the high and low pressure water pump device to be used for the test medium circulation storage.

● The pressure trial medium is water, air and kerosene that can be selected freely by users.

● During the course of presseure protection of water or air test, any button can not work under the condition of which the tested

valve cavity has high pressure, it can work nornmally until leaking the pressure to no pressure (make sure safety while working).

● The test bench is equipped with an automatic oil pressure discharge system. As it is used, a high pressure condition and pressure

discharge condition can be changed over to effectively reduce the oil temperature, elongate life of the test bench and save energy.

● It sets the pressure trial safe protective device.

● It can match with computer detection data management system.
