PRODUCT OVERVIEW
Ultra thin pneumatic ball valve is one of the ball valves. It is a short flange distance ball valve designed according to different space constraints on site. The ball core channel of the ball valve has rectangular, V-shaped and O-shaped shapes. It has the characteristics of compact structure, small volume, light weight and convenient installation. The valve takes compressed air as the power source, takes the cylinder as the actuator, drives the valve with the help of accessories such as electric valve positioner, converter, solenoid valve and holding valve, realizes on-off or proportional regulation, and receives the control signal of industrial automation control system to adjust various process parameters such as flow, pressure and temperature of pipeline medium. It can be widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to automatically regulate or cut off oil, water, gas, pulp or fibrous fluid.
PRODUCT FEATURES
1. According to the needs of users, anti-static structure can be set.
2. The valve seat adopts elastic sealing structure, with reliable sealing and easy opening and closing.
3. A 90 ° switch positioning piece with hole is set, which can be locked as required to prevent misoperation.
4. The utility model has the advantages of short structure length, light weight, convenient installation, material saving, etc.
5. It is equipped with fire-resistant structure, which can still operate reliably and have good sealing in case of fire.
