Product details
Imported precision small electric ball valve
Main features and uses of imported precision small electric ball valve
Precision small electric ball valve is suitable for occasions with two-position cut-off adjustment. The connection between the valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system. There is no need for an additional servo amplifier. The operation can be controlled by inputting signals and power. It has the advantages of simple wiring, compact structure, small size, light weight, light resistance and small movement, stable and reliable. The actuator can be equipped with a series of other types of electronic electric actuators or iso-pneumatic piston actuators according to user requirements.

Imported precision small electric ball valves have the following advantages
Small fluid resistance ball valves have the smallest fluid resistance among all valve types. Even if they are reduced diameter ball valves, their flow resistance is quite small.
The thrust bearing reduces the frictional torque of the valve stem, allowing the valve stem to operate in a balanced and flexible manner for a long time.
The valve seat has good sealing performance and uses sealing rings made of polytetrafluoroethylene and other materials. The structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
The valve stem seal is reliable. Since the valve stem only rotates and does not move up and down, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases as the pressure of the medium increases.
Because materials such as polytetrafluoroethylene have good self-lubricating properties, the friction loss with the ball is small, which helps the ball valve have a long service life.
