Choose high precision pneumatic actuators and pneumatic ball valve of precision casting ball valve. Key is divided into pneumatic sealing ball valves (200 ° or less) and pneumatic hard seal ball valve (550 ° or less). Pneumatic ball valve with compact structure, small volume, low operation by spectrum, the fluid density index, good sealing, maintenance is very easy and convenient installation, strong ability to adapt and other advantages. Pneumatic ball valve can match schedule trip switch, relay, pressure regulating valve stainless steel hydraulic fitting and pneumatic valve power switch operation can be completed, and sent out two passive contact data signals to the power switch of gate valves. Pneumatic ball valve manufacturer points out that the pneumatic ball valve is particularly appropriate for flange plate material is thick, containing particulate matter, chemical fiber properties.

Pneumatic ball valve flange plate is especially appropriate in material is thick, containing particulate matter, chemical fiber properties. Pneumatic ball valve stainless steel tube fitting manufacturer said pneumatic ball valve is widely used in oil, chemical plant, teaching equipment, light industrial machinery and equipment, high pressure, the pharmaceutical industry, papermaking industry and other industrial production of fully automatic automatic control system, the long-distance centralized control system or in situ manipulation.
(1) liquid friction resistance, small ball valve are all valve class Z less liquid friction resistance in a, even reducing ball valve, the liquid friction resistance is very small.
(2) reduce stem friction torque thrust bearing, can make the valve stem long-term practical balanced spirit.
(3) high pressure gate valve good sealing performance, choose the ptfe sealing ring made of raw materials, is advantageous for the sealing structure, and with material working pressure stainless steel needle valve ball valve valve sealing ability of adding and expand.
(4) stem seal, because the stem for rotation exercise and not only do the elevator fitness, filling material of valve stem seal is not easy to damage, and sealing ability is accompanied by adding material work pressure and expand.
(5) because of superior since the wettability of the ptfe raw materials, such as, with a small ball friction damage, for ball valve with long term.
