| Plug Valve |
 ¡¡¡¡Plug valve is a necessary part that is connectedwith high-pressure manifold in operation of cementingwell and fracture in oil field and also suitable to gigh-pressure fluid control. As plug valve assembling, thesealing surfaces were coated with high pressure greasemade in USA and each valve was hydrostatic tested onstrength and seal and no-leakage valve was permittedto provide to user. It features compact structure, conve-nient maintenance, small torque, rapid open and simpleoperation, so it is the best valve in cementing/ fracturemanifold.
Plug valve mainly consists of valve body, handwheel, piston and etc.
The outlet adopts union 1502 connection (also or-dered as required by user) and column fitting exits between the valve body and liner, the outer circle of whichis sealed with seals mounted.
Between liner and piston is sealed with columnmetal fitting and it features high fitting precision and re-liable seal.
Notice: Under the 10000PSI pressure, the valvecan be easily opened or closed.
Operation & Application
Plug valve shall be clean and high-pressure greaseshall be injected into valve chamber in time, otherwisethere may be leakage on the outlet.
Before usage, it should be inspected whether theopening/closing situation be in line with sign and handwheel turning at 90 degree can create open/close.
The clean and injection of oil/grease should be ex-ecuted after work is over. Regularly check whether all seals is damaged, the dam-aged seal should be replaced immediately; As the seal of the piston and liner fail, it should be dis-assembled and inspected, it can be polished or replaced.
