4, the valve stem is tightly closed good, because the valve stem will only be used as rotation and don't do up and down movement, the valve stem packing tightly closed is not easy to damage, and tightly closed experienced increases as the medium pressure increases. Itself, the application of the pneumatic ball valve, ball valve structure is compact, tightly closed reliable, simple structure, convenient maintenance, often in the closed tightly closed surface and the ball surface, not easily be medium erosion, easy operation and maintenance, suitable for use in water, solvents, acids and natural gas and other medium of general office, and also suitable for use in conditions of despicable medium, such as oxygen gas, oxygen, hydrogen, methane and ethylene, etc. , in seventy-two won a wide range of applications. 5, because materials such as ptfe have satisfactory self lubricating oil, and the spherical stereo friction loss is small, so the use fixed number of year of the survival of the length of the pneumatic ball Industrial Valves. 7, anti-static function: between the spherical stereo, valve stem and valve body set up spring, can switch process initiation of electrostatic export. Ball valve body can be a group, also can be combined. 1, fluid resistance small, pneumatic ball valve is the valve all classification of least resistance of fluid, even reducing pneumatic ball valve, the fluid resistance is small. 。 Pneumatic ball valve's unique place: pneumatic ball valve is mainly used to cut off or connect pipe in the media, can also be used for the regulation of fluid and stem, pneumatic ball valves and other valves by category, with output torque Angle trip, open the speed, safe and secure reliable, suitable for use is widespread, such as the following strengths. Q: shallow talk about the unique place and application of the pneumatic ball valve a: pneumatic ball valve is composed of ball valves equipped with decorate a pneumatic actuators, pneumatic actuators are divided into double effect with pneumatic actuator and the utility model of pneumatic actuator, electric current magnetic valve stem, successful implementation ball valve switch. Ball Industrial Valves in the line is mainly used to do truncation, distribution, and changes the flow direction of medium, it takes with the operation of the rotated 90 degrees and small rotational torque can close the tightness. Ball valve is the most fitting for do switch, block valves apply, but recent developments have ball valve preset into with throttling and stem flow, such as V type ball valve. 3, seat tightly sealed performance is good, see fit and use of elastic materials such as ptfe tightly closed circle Marine valve, facilitate tightly closed structure, pneumatic ball valve of the valve closure and experienced increases as the medium pressure increases. 2, thrust bearing, reduce the stem friction torque, can make the valve stem operation safe and secure for a long period of time. 6, unloading valve stem and valve stem head convex order to avoid the valve stem, such as fire cause stem tightly closed mutilate, convex order between the body and also can form metal contact, ensure that the valve stem tightly closed. Can successfully implement intelligent pneumatic ball valve stem, quickly turned on or off line, can work on pipe network of stem and management. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
