Q611F pneumatic three-piece ball valve is a small ball valve, is composed of three parts of the valve shell, by four longer bolts from both ends of the intermediate valve body and valve ball and become. The advantage is that the maintenance and disassembly without disassembling the pipeline threads, but directly disassemble the four bolts, the middle part of the valve body can be taken out. It is characterized by reasonable structure, beautiful shape, easy opening and closing, reliable sealing and so on. Pneumatic three-piece ball valve is suitable for working pressure PN16, working temperature ≤ 120 ℃ of various pipelines, used to cut off or connect the medium in the pipeline. Different materials can be used for water, steam, oil, nitric acid, acetic acid, ammonia brine, neutralized water and other media.
Working Principle
Pneumatic three-piece ball valves drive the rotation of the ball body through the 90° rotation of the pneumatic actuator to achieve the circulation and blocking of the medium. The direct connection between the actuator and the valve body reduces the chance of failure, and is suitable for light machinery with small volume and narrow space. The valve stem adopts the lower mounted structure with inverted seals When the valve cavity is abnormally pressurized, the valve stem will not be shocked. A 90° switch positioning mechanism can be set up, and locks can be added as needed to prevent misoperation.
