V47 Series:Temperature Actuated Water Regulating Valve


The V47 is a temperature actuated modulating valve that regulates the flow of water or glycol to maintain a desired temperature. Three temperature ranges for each valve size are available.

Many valves come with a removable bypass plug that can be replaced by the bypass orifice provided separately with each valve. Valve action is open on temperature increase. For open on temperature decrease models, contact Application Engineering.
