The valve is a three-way shutoff valve for refrigerating or air-conditioning systems. It is designed for the installation of two safety valves in a system and makes it possible to replace the de-pressurized safety valve while the system continues running. According to DIN EN 378-2
the valve can only be handled with a tool. The valve has one inlet and two outlets. In end position the spindle always closes up one of the two outlets.
