Chief Features
During the opening and closing of the valve, the sealing surface of the valve body has no contact with the sealing surface of the sliding vane. Therefore, the sealing surface has no friction and wear, the service life of the valve is long, and the opening and closing torque is small
During the maintenance of the valve, it is not necessary to remove the valve from the pipeline, but only to remove the valve bottom cover and replace a pair of slide plates, which is very convenient for maintenance;
The valve body and plug are full port, the medium has no flow resistance when passing through the valve, and the pipe can be cleaned through the ball, which overcomes the shortcomings of the reducing valve;
The valve is equipped with relief device (optional) to prevent abnormal pressure rise in the valve chamber and check the effect of the valve after the valve is completely closed;
The sealing of the valve is achieved by the sealing ring around the valve. It has particular protection of swallow-tailed sink and fixed sealing rings.
Operation Principle
When the plug valve is fully open, the channel is in alignment with the channel of valve body,which can ensure ideal and lowest pressure drop.
When the handwheel is turned,the plug will rotate toward the closing direction,and at the same time draft the rotation of the valve disc by 90°.When the handwheel is turned further on,the plug will pressured down,and make the valve disc open to two sides,so that the valve disc will be firm contact with the valve seat and close the valve.
When the handwheel is turned inversely,first of all the plug will move upward,and the valve disc and valve seat will be separated,second the handwheel shall be turned further on,till the valve disc is turned by 90°driven by the plug,finally the channel of plug will be in alignment with the channel of valve body,the valve is fully opened.

Trunnion Type Ball Valve
Product Description:
main feature
1. Effortless operation: The ball is supported by upper and lower bearings, which reduces friction and eliminates the huge sealing load caused by the inlet pressure pushing the ball and the seal seat.
Excessive torque.
2. Reliable sealing performance: The PTFE single material sealing ring is embedded in the stainless steel valve seat. A spring is provided at the end of the metal valve seat to ensure sufficient pre-tightening force of the sealing ring. The valve
When the sealing surface wears during use, the valve continues to ensure good sealing performance under the action of the spring.
3. Fireproof structure: In order to prevent the polytetrafluoroethylene sealing ring from burning due to sudden heat or fire, resulting in larger leakage and fueling the fire, the ball and valve are
A fireproof sealing ring is set between the seats. When the sealing ring burns out, the valve seat sealing ring is quickly pushed onto the ball under the action of spring force, forming a metal-to-metal seal.
Sealing, achieving a certain degree of sealing effect. The fire resistance test meets the requirements of APl6FA and APl607 standards.
4. Automatic pressure relief function: When the stagnant medium pressure in the middle cavity of the valve rises abnormally and exceeds the pretightening force of the spring, the valve seat retreats away from the ball to achieve automatic pressure relief.
As a result, the valve seat automatically resets after pressure relief.
5. Drainage pipeline: Drainage holes are provided on the upper and lower sides of the valve body to check whether the valve seat is leaking. During operation, when the valve is fully open or fully closed, remove the middle chamber pressure
Force, the packing can be replaced directly; the residue in the middle cavity can be discharged, reducing the contamination of the valve by the medium.

Chief Features：
Compared with floating ball valve, when working, all the forces generated by the fluid pressure in front of the valve on the ball are transmitted to the bearing, which will not make the ball move towards the valve seat, so the valve seat will not bear excessive pressure.And the torque of trunnion ball valve is small, the valve seat deformation is small, the sealing performance is stable, and the service life is long, which is suitable for high-pressure and large-diameter occasions. Advanced spring pre-seat assembly with self-tightening feature realizes upstream sealing. Each valve has two seats, which can be sealed in each direction. Therefore, there is no flow restriction for installation, and it is bi-directional. The valve is generally installed horizontally.
