Stainless steel electric ball valve products overview

　　Electric ball valve is a kind of Angle is 90 ° rotation type valves, sealed performance is good, flow coefficient, flow resistance coefficient is small, simple structure, long service life and easy maintenance. With cylinder actuators, electric ball valve shuts off and adjust the two models. Products are widely used in chemical, petroleum, textile, electricity, food, pharmaceutical, refrigeration, control system in papermaking industry. Flange connection line can maintain good sealing performance, easy replacement of maintenance, facilitate line closed.

　　Stainless steel electric ball valve product characteristics

　　1, small fluid resistance, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small.

　　2, thrust bearing, reduce the stem friction torque, can make the valve stem long flexible operating balance.

　　3, seat sealing performance is good, use the materials such as ptfe sealing ring, the structure is easy to seal, and the ball valve seal ability increases with the adding of medium pressure.

　　4, the valve stem seal is reliable, because the valve rod rotation movement and not only do the lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increase with the pressure increasing and medium.

　　5, such as ptfe material has good self-lubrication, and small sphere of the friction loss, help ball valve's service life is long.

　　6, bottoms type valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the valve stem seal.
