Mikuni's Gas Control Valve is a dedicated accessory for household fuel-cell cogeneration systems (Ene-Farm). It controls city gas within the fuel-cell system and uses an automotive-derived stepping motor to improve reliability. Mikuni also uses a nozzle-system design that allows the required valve characteristics to be achieved by varying the valve configuration. The product is manufactured by Mikuni Corporation in Japan and is specifically identified by the manufacturer for home fuel-cell applications. Detailed pressure, flow and dimensional specifications are available only by enquiry.
