◆ Working principle: 

 When the pneumatic actuator receives a signal from the control system, the compressed air enters the cylinder of the actuator to push the piston to move. The piston drives the valve stem to rotate through the connecting mechanism, which moves the valve core in the valve seat to open or close the valve. The signal feedback device detects the position of the valve stem or valve core and feedbacks the actual state of the valve to the control system in the form of electrical signals, so that the operator can understand the working situation of the valve in real time. 

 ◆ Technical parameters: 

 Pressure range: generally around 0 - 16bar. 

 Medium temperature: usually between -10℃ and +180℃, some high-temperature types can reach higher temperatures. 

 Ambient temperature: generally - 10℃ - +60℃. 

 Valve body and valve core material: mainly stainless steel 304, 316, etc. 

 Sealing material: Polytetrafluoroethylene (PTFE) is mostly used. 

 Actuator shell: usually made of polyamide and other materials. 

 Air source pressure: double action is generally 3 - 8 bar, and single action is 4 - 8 bar. 

 ◆ Application field: 

 It is widely used in the food and beverage industry, such as the filling production lines of beer and beverages; drug production, disinfection and sterilization equipment in the pharmaceutical industry; dyeing and bleaching equipment in the textile printing and dyeing industry; vulcanization equipment in the rubber machinery industry; various reactors and pipelines in the organic and inorganic chemical industries; cleaning, disinfection and high-temperature sterilization equipment And water treatment system, etc. It is suitable for situations where the medium is water, liquid, neutral gas, water vapor, slightly corrosive gas and liquid, etc.

Each process, each facility, and each environmental constraint has its own special requirements. As a result, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions and materials.
