Product features

The pneumatic high platform ball valve adopts the high platform ISO5211 standard design. It is a connecting plate set to facilitate the ball valve to install the driving device. It can be directly installed with the actuator without any support. The ordinary 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 rate. It can not only be used to cut off the switch, but also to adjust the flow rate. 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 occasion where the medium temperature is too high to avoid damaging the actuator due to high temperature.
 
Features of pneumatic high platform ball valve:
 
1. High belt platform design, actuator and ball valve connection without bracket and connecting shaft, easy to install.
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 quick to open and close. Only 90 ° rotation is needed from full opening to full closing, which is convenient for remote control.
4. When the valve is fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the valve sealing surface when the medium passes through.

Working principle of pneumatic high platform ball valve:
 
Pneumatic high platform ball valve uses compressed air as power source, cylinder as actuator, and uses electrical valve positioner, converter, solenoid valve, retaining valve and other accessories to drive the valve to realize switch value or proportional regulation, and receive control signals from industrial automation control system to adjust various process parameters such as pipeline medium flow, pressure and temperature. The pneumatic actuator can be divided into single acting and double acting. The single acting actuator has the function of spring return, which can automatically reset to the initial state in case of failure due to loss of air supply
