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.
