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 pr

Globe valves are used for full opening or full closing. According to its function, it cannot be used as a throttling. Because in this case, due to the violent vibration when the medium passes through, the disc of the stop flash valve may be damaged and an accident may occur. However, the valve flap design of the throttle valve should consider the sealing performance when it needs to completely close the incense. T
