Air Control Valve

VFA Series Air Valve

Air Valve die-casting pneumatic valve which is controlled by an air signal is applied to the places where power is restricted. Simple structure, and reliable performance, and is widely used in inflammable, explosive places. A variety of specifications can be chosen.

VFA Series solenoid valves use a working pressure of 0.15 to 0.9MPa, the operation mode is internal pilot, the maximum operating frequency is 5 times per second, and the medium temperature is between minus 5 degrees to 60 degrees.

The element that controls and regulates the flow of compressed air is called the flow control valve. The element that changes and controls the direction of airflow is called the direction control valve. In addition to the above three types of control valves, there are logic components that can realize certain logic functions, including the immovable parts in the components of the jet element and the movable parts of the pneumatic logic components. In structural principle, the logic element is basically the same as the direction control valve, only the volume and diameter are smaller, generally used to achieve the signal logic operation function.
