1.Pneumatic clamp type thin ball valvesummary:
　　

Q671FThe clamp thin pneumatic ball valve is a new generation of ultra short flange distance ball valve developed by introducing Italian technology for domestic design. The shape of the ball core channel includes rectangularVForm andOForm. This series of products has the characteristics of compact structure, small volume, light weight, and easy installation, and can be widely used in the fields of petroleum, chemical, metallurgy, power plants, light industry, etc. It can automatically adjust or cut off oil, water, gas, pulp or fibrous fluids.
　　

Q671The pneumatic ball valve is composed of a pneumatic dual piston gear rack actuator and an ultra short flange distance ball valve. The valve body is the same as“1”The electric ball valve body is the same.
Pneumatic piston actuators are divided into two types: spring-loaded and springless. When the valve is required to be fully open or closed in case of a fault, a spring-loaded system (relying on the restoring tension of the spring to reset) should be installed. When the valve is required to maintain its position in case of a fault, a springless system should be installed. It is mainly composed of cylinder block, spring, piston, piston rod, front and rear cylinder heads, rack, output shaft and other components. For two switch valves, solenoid valves and travel switches are required; A comparative example regulating valve requires a locator.

The valve body adopts an integral structure. Through precise machining and assembly, the ball core is installed from one end and the pressure ring is tightened to maintain good contact and sealing between the two soft seal valve seats and the ball core. At the same time, the inner gasket of the pressure ring also achieves good sealing, ensuring zero leakage during valve operation. Due to the use of a monolithic valve body structure, this valve achieves ultra short flange spacing and greatly reduces the overall weight, making it only comparable to similar ordinary ball valves50%左右。
