OVIKOTOP ENTRY BALL VALVE1.One piece body
3.Low operation torque
Compound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.
The seat sealing is formed by seat sealing and metal retainer component.The seat retainer floats axially and low pressure sealing of valve seat is reached by pre-pressure of spring.In addition,the piston effect of valve seat is designed reasonably,which realized high pressure sealing by the pressure of operating medium and realize the interception of retainer to form the sealing of the body.The expansion graphite ring is designed to realize sealing under fire condition.
When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices.In addition,the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat.
7.Anti-static and fire safe design
The fire prevention design of valve meets the requirement in API6FA/API607 standard and the design of the anti-static conforms to regulations in API6D and BS5351.
For the underground installed valve,the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.
9.Various driving types
The top pad of valve designed according to ISO 5211,which is convenient for connection and exchange of various drivers.The common driving types are manual,electrical,pneumatic and pneumatic/hydraulic.
