Detailed introduction
Forged steel fixed ball valves, forged materials can ensure sufficient hardness and strength under maximum rated operating pressure without inherent defects. Adequate wall thickness determines the body and ADAPTS to different high-strength bolt valve systems for easy maintenance and well-designed valve internals sufficient to bear pressure piping valves, selected for reliability in a variety of working conditions.

2. Fire safety structure
When the trunnion ball valve is used normally, it is capped with seat and spherical method, seat retainer O-ring and stamped body, which is soft seal and seals reliably when the seat and O-ring are injured, seat retainer and body will be capped with expanded graphite such behavior for fire safety purposes.

3. Esd devices
In order to prevent the friction between the ball, rod and teflon generating static electricity that may ignite flammable items and explosives, resulting in accidents, in this ball valve, static conduction springs between the stem and the ball, the stem and the body so static electricity is a guarantee for ground and system safety.

4. Free leakage of body seal structure
Smooth, valve switch position valve body and cap double cap gasket and O-ring, on this basis, such reasons such as fire, high temperature, shock absorption and uneven opening or closing torque will not cause external leakage.

5. Operate low torque
Self-lubricating bearings are mounted on the friction stem cells, resulting in wear resistance, flexible operation and low torque.

6. Double Blocked Seepage (DBB)
When the ball is fully open or closed in position, the transmitter material body can be released in the center of the cavity for draining and empting devices. In addition, the very center pressure valve inside the cavity can be released to the low pressure end of its rescue seat.

7. Emergency seal
Composite injection hole design and composite injection valve mounted on the stem/cap and body side of the support valve when the seal stem or seat damage induced leakage, this compound can be used to do a second seal concealed check valve mounted next to the compound injection valve to prevent the rapid connection of the compound injection valve on the top of the compound due to the action of the compound compound Connect the connector injection gun.

8. Expand the stem
Underground installation valve, valve stem can be extended, for easy operation of the corresponding compound fuel nozzle, drainage valve can be extended to the highest valve.

9. Automatic body cavity, rescue
When the body pressure rises abnormally, such as unstable factors, the downstream seat of the trunnion ball valve will be under normal pressure, and the abnormal pressure will be automatically released without damaging the upstream seat of the seal.

10. Various drive types
Valve top pads are designed according to ISO 5211 for easy communication and connection of various drives Common drive types are manual, electric, pneumatic, pneumatic/hydraulic.
