The pneumatic ball valve refers to the ball valve with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast, and the fastest switching speed can reach 0.05 seconds/time, so it is usually called pneumatic fast cutting ball valve.
The pneumatic ball valve is generally not used alone, usually configured with various attachments, such as solenoid valve, gas source treatment three connections, limited switches, locations, control boxes, etc. In the control room, the switch of the valve can be directly controlled. It is not necessary to run to the scene or high -altitude and danger to bring manual control, which largely saves human resources and time and security.
There are many types of pneumatic ball valves, but they can still be divided into O -type ball valves and V -type ball valves. The following pneumatic ball valve manufacturers will introduce the differences between these two ball valves.
The aerodynamic O -type ball valve adopts a floating structure, the core of the ball is precision casting, and the appearance is hard chromium. The valve seat is enhanced the polytrafluoroethylene material. No leakage, generally used for switch valve, especially suitable for high -viscosity fluid media; while V -type ball valve adopts a fixed structure, a V -shaped incision is opened on the core, which can achieve fibrous and granular media. In addition, pneumatic or electric execution agencies can be selected according to different process equipment to form pneumatic ball valves and electric ball valves.
