Electric flange ball valve
details
The detailed information
Description

Q941 electric flange ball valve is mainly used to cut off or close the medium in the pipeline, and can also be used for fluid regulation and control. It has the following advantages compared with other valves.

1, the fluid resistance is small, the ball valve is the least one of the fluid resistance of all valves, even the reduced diameter ball valve, its fluid resistance is quite small.

2, the thrust bearing reduces the friction torque of the valve stem, which can make the valve stem balance and flexible for long-term operation.

3, the valve seat sealing performance is good, the sealing ring made of PTFE 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.

4, the valve stem seal is reliable, because the valve stem only rotates without lifting movement, the packing seal of the valve stem is not easy to break, and the sealing capacity increases with the pressure of the medium.

5. Since the material such as polytetrafluoroethylene has good self-lubricating property, the friction loss with the sphere is small, and the service life of the ball valve is long.

6, the bottom-mounted valve stem and the stem of the valve stem prevent the valve stem from being sprayed out. If the valve stem seal is broken due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem is sealed.

Q941F/PPL stainless steel electric ball valve is a kind of rotary valve with 90° rotation angle. It has excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance. Equipped with an electric cylinder actuator. Products are widely used in chemical, petroleum, textile, power, food and pharmaceutical, refrigeration, paper industry system control.
