Product features

The pneumatic high platform ball valve adopts the high platform ISO5211 standard design. It is a connecting disc set to facilitate the installation of the drive device of the ball valve. It can be installed directly with the actuator without the need for a bracket. The common ball valve needs a bracket and connecting shaft support between the connection and the actuator. The pneumatic high platform ball valve has the characteristics of small flow resistance and large flow volume. It can not only cut off the switch, but also be used to adjust the flow. The valve body and valve seat of different materials can be used in different working conditions. Due to the short distance between the high platform ball valve and the pneumatic actuator, it is not suitable for the occasions where the medium temperature is too high to avoid damaging the actuator due to high temperature.
 
Features of pneumatic high platform ball valve:
 
1. The high belt platform design is adopted, and the connection between the actuator and the ball valve does not need a bracket and a connecting shaft, which is convenient for installation.
2. The structure is simple, compact and reliable, and there is no need to add connecting parts to improve the stability of product operation.
3. It is easy to operate and can be opened and closed quickly. It only needs to rotate 90 ° from full opening to full closing, which is convenient for remote control.
4. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.

Working principle of pneumatic high platform ball valve:
 
The pneumatic high platform ball valve uses compressed air as the power source, air cylinder as the actuator, and uses electrical valve positioner, converter, solenoid valve, retaining valve and other accessories to drive the valve to achieve on-off or proportional regulation, and receives the control signal from the industrial automation control system to complete the regulation of various process parameters such as the flow, pressure, temperature of pipeline media. The pneumatic actuator can be divided into single action and double action. The single action actuator has the function of spring return, which can automatically return to the initial state in case of failure of air supply goods
