Electric hard seal flange ball valve has the same 90-degree rotation, with a circular through hole or channel 

passing through its axis. The ratio of the spherical surface and the channel port should be such that when 

the ball rotates 90 degrees, the inlet and outlet All places should be spherical, so as to cut off the flow. The 

electric flange ball intrusion only requires a 90-degree operation and a small torque to close tightly. The 

completely equal valve cavity provides a small resistance and straight flow path for the medium. It is usually

 considered that the ball valve is most suitable for direct opening. Closed use, but in recent years, the 

development of the ball valve has been designed to make it have the purpose of throttling and flow control.

 The main feature of the ball valve is its compact structure, easy operation and maintenance, suitable for

 general working media such as water, solvents, acid and natural gas, and it is also used for media with 

harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc. 

1. Thrust bearing reduces the friction torque of the stem, which can make the stem operate smoothly and 

flexibly for a long time.

2.Stem seal is reliable, because the stem only as a rotating movement and do not do lifting movement, 

stem packing seal is not easy to damage, and the sealing capacity increases with the increase of medium

 pressure.

3. The fluid resistance is small, ball valve is all kinds of valves in the fluid resistance of the smallest, even 

if it is a reduced diameter ball valve, the fluid resistance is also quite small.

4. The valve seat sealing performance is good, using ptfe and other elastic materials made of the sealing

 ring, the structure is easy to seal, and the ball valve sealing capacity increases with the increase of 

medium pressure.

5. Due to the ptfe and other materials have good self-lubrication, friction loss with the ball is small, so the 

service life of the ball valve is long.

6. Lower mounted stem and stem head convex step to prevent stem ejection, such as fire caused by stem

 seal damage, convex step and valve body can also form a metal contact, ensure stem seal.

Fine small series electric actuator are used to control 0-90° rotation valve and other similar products such 

as butterfly valve, ball valve, throttle plug valve, louver valve, etc . It uses AC24V, 220V ,110V, 380V , and 

DC 24V voltage to be the driving source, 4-20mA current signal or 0-10V voltage signal to the controlling 

signal driving the valve to the required position, so that realized the automation control.

They can be widely used in petroleum, chemical,electric power, metallurgy, papermaking, water treatment, 

shipbuilding , food processing and building automation. At the same time, it has the advantages of small 

size, light weight , beautiful appearance , unique structure , compact structure, quick opening and closing,

 easy installation , small operating torque, convenient operation, no need for maintenance and safe  and 

convenient use of digital display valve position.
