Pneumatic ultra-thin ball valve (also known as pneumatic clamp ball valve) is the introduction of Italian technology for the localization of the design and the development of a new generation of ultra-short flange distance ball valves, is composed of a single (double) action piston type pneumatic actuator and ultra-thin ball valves. Pneumatic ultra-thin ball valve can be equipped with a valve positioner input control signal (4-20mADC or 1-5VDC) to control the operation of the gas source. Can also be equipped with travel limit switches, solenoid valves, pressure reducing valves and 0.4 ~ 0.7MPa gas source can be realized switching operation, and send out two pairs of passive contact signals to indicate the valve switch. Pneumatic ultra-thin ball valve (pneumatic clamp ball valve) ball core channel shape rectangular, V-shaped and O-shaped. This series of products has a compact structure, small size, light weight, easy to install and so on. Therefore, pneumatic ultra-thin ball valve (pneumatic ball valve) is widely used in petroleum, chemical, metallurgy, power station, light industry and other fields, oil, water, gas and pulp or fibrous fluid for automatic adjustment or cut off control.
