Pneumatic ball valve includes valve body, ball, valve stem and pneumatic actuator. A bracket is arranged on the valve stem between the valve body and the pneumatic actuator. The valve stem between the bracket and the valve stem is sequentially provided with a packing gland, a packing and a packing pad from bottom to bottom. A sliding bush is arranged between the valve stem and the valve body, one end of the valve bod

Electric actuator is a commonly used transmission device in industrial production systems. The main function of this device is to control the transmission device, so as to complete various complex assembly line production tasks. Since it is directly related to the daily production of the factory, the quality of the equipment must be guaranteed during operation. Customers can judge according to the three aspects of eq

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

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

The solenoid valve is a solenoid valve that generates a magnetic force to attract and overcome the pressure of the spring to drive the valve core to move after the solenoid coil is energized. It is only a solenoid coil, which has a simple structure and a low price, and can only be switched. The valve is divided into (shut-off valve) and regulating valve. The shut-off valve is a two-position type of work, that is, fu

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external
