ductile iron Plug valve is a necessary part that is connected with high-pressure manifold in operation of cementing well and fracture in oil field and also suitable to high pressure fluid control. As plug valve assembling, the sealing surfaces were coated with high pressure grease made in USA and each valve was hydrostatic tested on strength and seal and no-leakage valve was permitted to provide to user. It features compact structure, convenient maintenance, small torque, rapid open and simple operation, so it is the best valve in cementing/ fracture manifold.
Plug valve mainly consists of valve body, hand wheel, piston and etc.
The outlet adopts union 1502 connection (also ordered as required by user) and column fitting exits between the valve body and liner, the outer circle of which is sealed with seals mounted.
Between liner and piston is sealed with column metal fitting and it features high fitting precision and reliable seal.
Notice: Under the 10000PSI pressure, the valve can be easily opened or closed.
Operation & Application
Plug valve shall be clean and high-pressure grease shall be injected into valve chamber in time, otherwise there may be leakage on the outlet.
Before usage, it should be inspected whether the opening/closing situation be in line with sign and hand wheel turning at 90 degree can create open/close.
Maintenance
Constant maintenance can prolong the working life of valve;
The clean and injection of oil/grease should be executed after work is over.
Regularly check whether all seals is damaged, the damaged seal should be replaced immediately;
As the seal of the piston and liner fail, it should be disassembled and inspected, it can be polished
