DSG is a quick open shut off valve for low pressure gas. It is NC type (open when energized) for city gas, natural gas and LPG. Ports are Rp1/2, Rp3/4 and Rp1, and the working pressure is up to 5 kPa. The DC driven actuator with rectifier eliminates noise and coil burnout, and a strainer is built in.
