Pneumatic eccentric flange ball valve is a right-angle rotary control valve, which consists of a pneumatic actuator and a V-shaped ball valve. It is used together with solenoid valve and electric valve positioner. Input 4 ~ 20ma DC signal and 0.5 ~ 0.7Mpa air source can control the operation, and realize the adjustment of parameters such as pressure, flow rate, temperature, and liquid level. Because the pneumatic V-shaped regulating ball valve has a right-angle rotary structure, it has a strong shearing effect when the valve core rotates relative to the valve seat. It can be widely used in petroleum, chemical, light industry, power, pharmaceutical, papermaking, metallurgy and other industries In the automatic control system, it is used for centralized remote control or local control.
