1、 Overview of Pneumatic Clamp Ball Valve Products
The Q671F/PPL pneumatic clamp ball valve produced by Shanghai Yuhu Company is a product in the pneumatic ball valve series, also known as the pneumatic ultra-thin ball valve. It is a new generation of ultra short flange distance ball valve developed by our company through the introduction of Italian technology for domestic design. The ball core channel shapes include rectangular, V-shaped, and O-shaped. Pneumatic clamp ball valves have the characteristics of compact structure, small volume, light weight, and easy installation. Pneumatic clamp ball valve is a new type of ultra short flange distance ball valve developed by absorbing Italian technology and localized design. Pneumatic ultra-thin ball valve adopts a direct connection actuator connection, which has the advantages of compact structure, small size, light weight, low friction resistance, small backlash, stable and reliable action. Pneumatic ultra-thin ball valve can be widely used in petroleum, chemical, metallurgical, power station, light industry and other fields to automatically adjust or cut off oil, water, gas, pulp or fibrous fluids.
