Characteristics of explosion-proof pneumatic butterfly valve
It has circular through holes or channels. Through its axis. When the center of the ball rotates to 90 °, the valve is tightly closed. When the actuator is working, the valve can be closed tightly with only a small torque, thus realizing the principle of quick cut-off. Explosion proof pneumatic butterfly valve is mainly used for fast cutting, distribution and replacement of medium flow path. Explosion proof pneumatic butterfly valve can be quickly opened and closed, suitable for large diameter and small diameter. The medium flow can be accurately adjusted by using a V-shaped sphere.
There are two types of explosion-proof pneumatic butterfly valves. One is the O-ring, which is a floating precision casting with the same diameter as the pipe, and is mainly used as a cut-off switch. The other is a V-shaped spherical core, which adopts a fixed structure and has a V-shaped notch on the spherical core. After the positioner is installed on the actuator, the proportion of fiber and granular media can be adjusted.
