Plug valve is a key 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 feature compact structure,convenient maintenance,small torque,rapid open and simple operation.So it is the better 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 linter,the outer circle of which is sealed 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 valve chamber in time.Otherwise there may be leakage on the outlet .
Before usage,it should be inspected whether the opening/closing 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 cf 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 or replaced.
