2/2 way Pneumatic flange

Product overview
Pneumatic ball valve is an important actuator in industrial automation control system.His Pneumatic valve seat Change is relation with directly proportional valve stroke.Mainly used for truncated or on line in the medium,as well Can be used for the adjustment and control of the fluid, is one of the industrial automation process control piping components 90° is a corner to realize the opening and closing the Pneumatic ball valve of ball valve, it has a large flow capacity,flow resistance Several small, simple structure, convenient maintenance, long service life, etc.The body channel and the connection pipe diameter in the same center line, through the medium can be almost no losses.This product is often used to seal the demand is higher Place, in addition to the general fluid control, also suitable for control of sewage and fibrous impurities of medium,Widely used in petroleum, chemical, metallurgy.Power stations and other work areas.
Product characteristic
1.Applicable for pipe a big pressure difference , strict sealing of theswitch and cut off the pipeline medium process and the fluid flowcontrol system.
2.Applicable for different kinds of fluid medium and realize 2-way flow.
3.Fluid resistance small, ball valve is the smallest of all valve fluidresistance class.
4.The seat sealing performance is good, use TEFLON as sealing ring,structure is easy to close seal and ball valve sealing ability increasesas the pressure medium.
5.As the seal ring has good lubrication, the sphere of the frictioncoefficient is small, extend the ball valve life.
6.Bottoms type valve stem and the head of valve stem head is specialdesign, such as fire stem seal damage, the valve stem Convex setsand the body can also be formed between the metal contact, to ensure that the valve stem seal.
