Characteristic of Trunnion Mounted Ball Valve Construction Machinery
Although there are many types of trunnion mounted ball valvesproducedby trunnion ball valve supplier, they all have the following ball valve characteristics:
- Its operation is labor-saving: the ball is supported by upper and lower bearings, which reduces friction. It eliminates the excessive torque caused by the enormous sealing load formed by the sphere and seal seat driven by the inlet pressure.
- Fire-proof ball valve construction: In order to prevent the PTFE sealing ring from burning down due to sudden heat or fire, and to increase the fire potential, a fire-proof sealing ring is set between the sphere and the valve seat. When the sealing ring is burned down, under the action of spring force, the seat sealing ring is quickly pushed onto the sphere to form a metal and metal seal. It has a certain degree of sealing effect.The refractory test meets the requirements of APl6FA and APl607 standards.
- Automatic pressure relief function: When the medium pressure in the stagnant chamber of the trunnion mounted ball valveincreases abnormally beyond the pre-force of the spring, the seat retreats away from the ball to achieve the effect of automatic pressure relief, and the seat is automatically restored after pressure relief.
