GB641J often closed type pneumatic diaphragm valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valves and pneumatic diaphragm valve GB641J often closed different effects, from ball valve and pneumatic diaphragm valve structure GB641J often closed up. 【 Functional difference between 】 GB641J often closed type pneumatic diaphragm valve is opened and closed by a pneumatic actuators to drive the up and down movement of the Industrial Valves stem. When in the upper stem, spherical valve diaphragm upward bending forming conducting state. When the valve stem by drives the valve core movement down make diaphragm bending, forced to diaphragm tight seating area or, shut down the pipeline flow leads to the path. Used to control the corrosion or general corrosive medium, the valve body cavity surface without lining or covered with a selection of all kinds of rubber, suitable for different working temperature and fluid lines. Ball Industrial Valves and pneumatic diaphragm valve GB641J often closed difference is bigger, ball valve, 球阀) Opening and closing is a sphere, driven by the valve stem, and for ball valve axis rotate 90 & deg; Open or closed. Can also be used on regulation and control of fluid, mainly used for cutting in line, distribution, and change the flow direction of medium, good sealing, convenient operation, opening and closing fast, simple structure, small volume, small resistance, light weight, etc. 【 Physical difference between 】 Pneumatic diaphragm valve 【 GB641J often closed Summary 】 GB641J often closed pneumatic diaphragm valve and ball valve and using the difference function, are quite different in application, in the selection of a certain need to pay special attention to diameter, pressure, material and use of media, whether at design time, or in the purchase, must be in strict accordance with the relevant technical requirements.
