Product Description
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.

Ball valve accessories
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.
