O-type ball valve: it can adjust and cut off, and is commonly used for two position control. Its flow path is simple. When it is fully opened, a straight pipe channel is completely formed, and the pressure loss is small. It is especially suitable for high viscosity, suspension, pulp and other fluid occasions. Reliable sealing, small leakage, soft sealing ball valve can achieve bubble level sealing.

Main component 1: valve positioner The most important part of the pneumatic ball valve is the pneumatic actuator, and the most important accessory of the pneumatic actuator is the valve positioner. Of course, it must be used together with the pneumatic actuator, mainly to improve the accuracy of the valve position, ensure that it is not affected by the imbalance of media, and also overcome the friction problem of the valve stem, Then ensure that the valve can be accurately positioned according to the signal of the regulator.
