Ball valves and plug valves are the same type of valve, the difference in its closing member is a sphere, the sphere around the center line of the valve body for rotation to achieve open, close a valve. Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of flow of media. Ball valve is a new type of valve widely used in recent years.

Product features

Advanced valve seat: the valve seat designed by gathering many years of experience in manufacturing ball valves to ensure valve sealing, low friction coefficient, small operating torque, a variety of seat materials, wide range of adaptability.

Switching the handle without error: the use of flat stem, and the connection of the handle will not be misplaced, so as to ensure that the handle indicates the switch state and the valve a speech.

Locking device: In order to prevent the valve from switching incorrectly, there are locking holes in the fully open and fully closed position of the valve to ensure that the valve is in the correct position.

Valve stem anti-flying structure: the valve stem is under mounted to prevent flying out under pressure, and at the same time can form metal contact with the valve body after fire to ensure the valve stem sealing.

Working principle

The working principle of the ball valve is to make the valve unobstructed or occluded by rotating the valve stem. Can be full bore ball valve, 90 ℃ angle, ball valve switch light, small size, can be made into a large caliber, sealing and reliable, simple structure, easy maintenance, sealing surface and the ball surface is often in the closed state, not easy to be eroded by the media, in various industries have been widely used.
