Characteristics and functions of HYDAC ball valve

Ball valves are used in pipelines to cut off, distribute, and change the flow direction of media. They only require a 90 degree rotation and a small rotational torque to close tightly. Ball valves should be used as switches and shut-off valves, with V-shaped ball valves. In addition to paying attention to pipeline parameters, special attention should also be paid to the environmental conditions in which electric valves are used. As the electric device in electric valves is an electromechanical equipment, its usage status is greatly affected by its usage environment. Under normal circumstances, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.

Good sealing performance; Due to the fact that the sealing of hard sealed ball valves is manually ground until the valve core matches the sealing ring before use. So his sealing performance is reliable.

Anti static function: Install springs between the ball, valve stem, and valve body to dissipate static electricity generated during the switching process.

Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, resulting in a long service life for pneumatic ball valves.

Low fluid resistance: Pneumatic ball valves are a type of fluid resistance in all valve classifications, even for reduced diameter pneumatic ball valves, their fluid resistance is quite small.

Reliable sealing of valve stem: Due to the fact that the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.

Good sealing performance of valve seat: The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing ability of pneumatic ball valves increases with the increase of medium pressure.

Light switch; Due to the use of a spring at the bottom of the sealing ring of the hard sealed ball valve to tightly hold the sealing ring and valve core together, the switch is very light when external forces exceed the pre tightening force of the spring.

The opening and closing element (ball) is a valve driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, among which the hard sealed V-shaped ball valve has strong shear force between its V-shaped core and the metal valve seat of the welded hard alloy, especially suitable for media containing fibers, small solid particles, etc. The multi way ball valve on the pipeline can not only flexibly control the merging, splitting, and switching of the flow direction of the medium, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to their driving methods.
