The H91 Series are 2-wire, electrically operated shutoff valves that automatically open and close on a demand signal from a thermostat or other controlling device. Those indicated as White Rodgers replacements replace their compression spring closing and soft seat construction features. These valves can be used for all gas-fired appliances with a maximum operating pressure of 1/2 psi.
