Pneumatic Actuated Gate Valve

South American Valve is a leading Pneumatic Actuated Gate Valve Supplier in Chile. A pneumatic actuated gate valve is a type of valve that uses compressed air or gas to control the opening and closing of the valve. It consists of a gate, which is a flat or wedge-shaped obstruction that slides across the flow path to control the flow of fluid.

The pneumatic actuator is responsible for operating the gate valve. It is connected to the gate and uses compressed air or gas to move the gate between the open and closed positions. When the actuator receives a signal to open the valve, it pressurizes the air chamber, causing the gate to move away from the flow path, allowing fluid to pass through. Conversely, when the actuator receives a signal to close the valve, it releases the air pressure, allowing the gate to move back into position and block the flow of fluid

South American Valve is a leading Pneumatic Actuated Gate Valve Supplier in Chile. Pneumatic actuated gate valves are commonly used in various industries, including oil and gas, chemical, water treatment, and power generation. They are known for their quick response time, reliability, and ability to handle high-pressure applications. These valves are often preferred in situations where remote operation or automation is required, as the actuator can be easily controlled using pneumatic signals.
