HK1 is a 2-position gas shut off valve with an integrated motor and hydraulic pump, for main gas lines. It is NC type (open when energized) for city gas, natural gas and LPG. Ports are Rp1 1/2, Rp2 and Rp2 1/2 (screw-in), 40A to 80A (JIS flange) and 100A to 200A (DIN flange). A flow rate controller and strainer are provided (no flow rate controller for 125A to 200A).
