SINGLE SOLENOID VALVE
A valve is a device that regulates, directs or controls the flow of a fluid (gases, steam, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve. More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
A solenoid valve is electromechanically controlled for the purpose of generating a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it. That then opens or closes the valve automatically.
Because of its versatility, a RATIONAL combi replaces several pieces of equipment in your kitchen, including convection ovens, tilting fryers, rotisseries, boilers, deep-fryers, and steamers because it does the work of all of them.
RATIONAL is also useful in a wide range of establishment types. From school nutrition, hospitality, or grocery to the independent restaurant looking to better maximize space, many foodservice operators across the industry use combi-ovens in banquet finishing, overnight cooking, mixed loads, baking, sous-vide, breakfast, smoking, and more. It is the perfect all-in-one piece of equipment for schools, hotels, country clubs, and restaurants for preparing meat, fish, poultry, vegetables, eggs, and even breads and desserts.
