Gas Valves for Sanitary Hot Water Units
CVI Gas Control
The Combined Valve and Ignition (CVI) system has been developed for appliances with an automatic ignition system like Sanitary Hot Water Units. The gas controls have been designed to have the S4565/S4575/S4585 series ignition control (see boiler electronics) attached directly to the valve. The combined system then provides programmed safe light up, flame supervision and regulation of gas flow to the main burner and/of pilot burner of the appliance. The automatic gas control comprises a standard body to which a range of features can be included to give various functional options. These options include servo pressure regulation, throttle valve regulation, fully adjustable softlite, gas/air control 1:1 or amplified and electrical high-low or modulating control to fulfil the complete range of control applications.
