Pneumatic control valve can be roughly divided into: pneumatic ball valve, pneumatic butterfly valve, pneumatic gate valve, pneumatic globe valve and so on. The first two are switch modes of angular stroke, and the latter two are switch modes of straight stroke.
Common angular stroke pneumatic devices can be divided into two categories: rack-type pneumatic actuators and fork-type pneumatic actuators. Both use air pressure to drive the valve in essence, but the fork-type pneumatic device is better than the rack-type pneumatic device.
The fork-type pneumatic device is small in size, small in internal friction, and lower in consumption. At the same time, the service life is much longer than that of the rack type, which can reach more than 1 million times.
