Principle:

Ball of the ball is floating, in the medium under pressure, can produce some displacement of the sphere and pressed in the export side of the sealing surface, to ensure the export side seal.

Floating ball valve of simple structure, good sealing, but the ball under the load of work all the media to pass the export ring, so to consider the ring material can withstand the work load of the media sphere, under high pressure shock, the ball may shift. The structure, typically used in low-pressure valve.

 

The main features of the valve itself is compact in structure, reliable sealing, simple structure, convenient repair, sealing surface and spherical often in the closed state, can not easily be medium erosion, easy to operate and repair, suitable for water, solvents, acids, and natural gas general working media, but also suitable for poor working conditions of media, such as oxygen,Cast Steel Trunnion Mounted Ball Valve, methane and ethylene, widely used in various industries. Ball valve can be integral, it can be modular.

Product features

1, in all kinds of valves, valve minimum flow resistance, full bore ball valve is opened, the sphere, the channel of the valve body and the connecting channel diameter is equal and a medium diameter, almost no loss of flow

2, ball valve rotating 90 ° can fully closed to open, quick open and close. With the same specifications of the valve, stop valve, ball valve is of small volume, light weight, convenient installation of pipelines

1, advanced seat: Design of poly years manufacturing experience and the Cast Steel Floating Ball Valve, to ensure that the valve seal, low friction coefficient, small operation torque, a variety of seat materials, adapt to a wide range of.

2, the switch handle unmistakable: the flat head stem, and the connection will not misplace the handle, so as to ensure that the switch state and the valve handle indication of a speech.

3, the locking device: to prevent the valve switch misoperation, the valve is fully open, fully closed position with a locking hole, to ensure that the valve is in the correct position.

4, the stem fly prevention structure: the stem for downloading, compressive fly out, also can be in after the fire, a metal contact with the body, to ensure that the valve stem seals.

5, the ball valve is provided with a circular through hole ball as the opening and closing parts, valve stem drive in ball around the valve stem Center for the 0~90 degree rotation, complete opening and closing function; has the advantages of compact structure of rapid switch characteristics, rotate 90 degrees, then close the valve, cut off the pipeline medium; sphere channel diameter and pipe diameter, flow resistance small, large flow capacity; stem for downloading, prevent the occurrence of the stem out of the accident, to ensure the safe use.

Suitable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.
