Lever Type Self-Closing Valve:

Design: These valves typically feature a lever that can be manually lifted or pressed to allow the flow of fluid or gas. When released, the lever returns to its original position, shutting off the flow automatically.

Operation: Users lift or press the lever to open the valve, and the lever returns to its original position once released, shutting off the flow.

Advantages: Easy to operate and intuitive for users. The lever provides good leverage for opening and closing the valve.

Button Type Self-Closing Valve:

Design: These valves feature a button that users press to open the valve. Once released, the valve automatically closes.

Operation: Users press the button to open the valve, and the valve closes automatically when the button is released.

Advantages: Offers quick and precise control over the flow of fluids or gases. The button mechanism can be ergonomically designed for ease of use.

Both lever type and button type self closing valves serve the same purpose of controlling flow and automatically closing afterward. The choice between the two depends on factors such as the specific application, user preferences, and ergonomic considerations.
