APPLICATION
The V4055 Gas Valve Actuator, in combination with a VE5000a, V5055 or V5097 Gas Valve, controls the gas supply to commercial and industrial burners. When replacing a V4034 with a V4055, the V5034 gas valve must also be replaced with a V5055 or V5097 gas valve.
FEATURES • The V4055 Actuator, when used with the VE5000a, V5097 or V5055 Valve, is rated for final safety shutoff service. • The V4055 Actuator can be used with the characterized guide model of the V5055 or V5097 Gas Valve to enhance lightoff smoothness.
