The Johnson Controls H91DG-2 Solenoid Valve is a gas control component used in compatible commercial ovens, grills, and cooking equipment. Operating at 25 volts, it regulates the flow of natural gas or LP gas by opening and closing in response to electrical signals from the control system. The valve features 1/2-inch FPT inlet and outlet connections, a normally closed configuration, and a 1/4-inch tab terminal for electrical connection. Rated for up to 240,000 BTU, it is commonly installed within gas supply circuits for foodservice equipment. Replacing a faulty valve restores proper gas flow management and burner control operation.
