Access to fluid systems in public places could potentially convert into costs and safety problems. In order to avoid unattended valves being left open with negative economic or environmental consequences, RuB developed the automatic self-closing valve.

The valve can be opened normally by rotating the handle 90° and when the user releases the handle, the valve shuts off automatically. Best solution for service stations, trucks, public areas, gardens. The same features are also useful in industrial applications, where a valve must not be left open unattended.
