Cast Steel Pneumatic Gate Valve is an automated control gate valve made with cast steel body and equipped with a pneumatic actuator. The valve uses compressed air as the power source and drives the valve stem through a pneumatic actuator to achieve opening and closing of the gate valve. Cast Steel Pneumatic Gate Valves feature small opening/closing torque, short opening/closing time, simple operation, and high degree of automation. They can achieve remote control and automatic control, and are widely used in automated pipeline systems in industries such as petrochemical, power, metallurgy, and water treatment, especially suitable for operating conditions requiring frequent operation or unattended operation.
