How do I use AV series soft start-up valves?

These valves are used to suppress sudden increases in the initial pressure of pneumatic systems.
When the valve is energized (or the manual button is turned ON), low-speed air supply is performed with the flow rate adjusted by the needle valve, and when the pressure on the outlet side of the valve exceeds a certain level, the main valve is opened to provide high-speed air supply.
When the valve is turned OFF, the outlet air is rapidly exhausted from the exhaust port.
