Cast Steel Floating Ball Valve With Flanged End

The side entry trunnion mounted ball valve has been designed two piece body type or three piece body type and with two floating seats, which are movable under the pressure of medium. Under the bottom of seats, seat pre-loading springs are positioned to ensure two floating seats can attach the ball’s surface tightly, other more, pressure of medium also can push seats to attach ball tightly to ensure sealing more reliable. The trunnion ball valve is equipped with a movable seat seal ring which can generate displacement under the pressure of medium. In case that any medium pressure exists, the pressure will press the valve seat seal ring onto the ball tightly, guaranteeing the sealing performance of the ball valve.

Cast Steel Floating Ball Valve With Flanged End


Advantages

1.The operation is labor-saving, the ball is supported by the upper and lower bearings, the friction is reduced, and the large sealing load formed by the ball and the sealing seat is pushed by the inlet pressure to cause excessive torque.

2.The sealing performance is reliable: ptfe single material sealing ring is embedded in stainless steel seat, the end of metal valve seat is equipped with spring to ensure enough pretightening force of sealing ring, when the sealing surface of valve is worn during use, the valve continues to ensure good sealing performance under the action of spring.

3.Widely used in food, medicine, petroleum, chemical, natural gas, iron and steel, environmental protection, papermaking and other pipeline media cut off or circulation. The device can also be injected with the corresponding cleaning agent or lubricant to clean the sealing surface.

4.Drain line: discharge line is set up up and down the valve body, can check whether the valve seat has leakage, in the work, when the valve is fully open or closed, the pressure of the middle cavity can be removed, and the packing can be replaced directly; the retained matter of the middle cavity can be discharged to reduce the pollution of the medium to the valve. Auxiliary sealing setup system (customer needs to be described at the time of ordering)

5.Fire prevention structure: in order to prevent the appearance of sudden heat or fire, the polytetrafluoroethylene sealing ring burns out, causes large leakage, and encourages the fire. Fire proof sealing ring is set between the sphere and the valve seat. When the sealing ring burns out, under the action of spring force, the valve seat seal ring is pushed quickly to the sphere to form metal and metal seal, which plays a certain degree of sealing effect. Fire resistance test meets the requirements of apl6fa and apl607 standards.
