Hydraulic properties of globe valve

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

The difference between solenoid valve and electric valve

Solenoid valve is a type of electric valve; it uses the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body, the coil is de-energized, and the valve core is retracted by the pressure of the spring. The electric valve simply uses the electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided in
