1.Easy operation:The ball is supported by upper and lower bearings,which reduces friction and eliminates excessive torque caused by the huge sealing load formed by the inlet pressure pressure the ball and the sealing seat.
2.Reliable sealing performance:PTFE single material sealing ring embedded in the stainless steel seat, the metal seat end is provided with a spring to ensure sufficient pre-tightening of the sealing ring, when the sealing surface of the valve is worn during use, the valve continues to ensure good sealing performance under the action of the spring.
3.The structure of the fire prevention: In order to prevent the appearance of sudden heat or fire, so that the PTFE sealing ring burned, large leakage, and fuel the fire,The fireproof sealing ring is arranged between the ball and the valve seat, when the sealing ring is burned, under the action of the spring force, the valve seat sealing ring is quickly pushed to the ball, forming a metal and metal seal, playing a certain degree of sealing effect.Fire resistance test conforms to APl6FA and APl607 standards
4.Automatic pressure relief function: When the pressure of the stagnant medium in the valve chamber rises abnormally beyond the preload of the spring,the seat recedes from the ball to achieve the effect of automatic pressure relief, and the seat automatically restores after pressure relief.
5.The discharge line:Discharge holes are arranged above and below the valve body to check whether the valve seat leaks, in the work, the valve is fully open or fully closed, remove the pressure in the cavity,the packing can be directly replaced,cavity retention can be discharged, reduce the medium to the valve pollution,reduce the contamination of the valve by the medium.
Trunnion mounted ball valve is suitable for general industrial pipeline,long line pipeline, high pressure medium pipeline and a variety of corrosive and non-corrosive media,widely used in chemical,metallurgy,petroleum and pharmaceutical.
