◆ Working principle: 

 When the air source enters the pneumatic actuator through the trachea, the pneumatic actuator generates thrust, causing the valve stem to rotate 90 degrees along the axis to realize the opening and closing of the valve, and the sealing ring ensures the sealing when the valve is closed. The signal feedback function is achieved by installing a limit switch on the valve. When the valve reaches a fully open or fully closed position, the limit switch is triggered and the electrical signal is fed back to the control system to inform the current position status of the valve. 

 ◆ Technical parameters: 

 Pressure range: generally 0-16bar. 

 Medium temperature: usually between -10℃-+180℃. 

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

 Valve body material: commonly stainless steel 304, 316. 

 Sealing material: PTFE is mostly used. 

 The shell of the actuator: generally polyamide. 

 Control pressure: usually between 3-8 bar. 

 ◆ Application field: 

 It is widely used in beer, textile printing, dyeing and bleaching, pharmaceutical and medical equipment, food processing, rubber machinery, organic and inorganic chemicals, cleaning, disinfection, high temperature sterilization, water treatment and other industries. It is suitable for situations where the medium is water, liquid, neutral gas, water vapor, slightly corrosive gas and liquid.

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.
