The VF Series electric actuated butterfly valves are designed for a wide range of HVAC applications, including two-position and modulating control of hot, chilled, or condenser water, and up to 50/50 glycol solutions. These resilient-sealed valves feature vulcanized liners, resulting in a more precise seal and lower operating torque. When coupled with VA5000 series actuators, these valve assemblies can also achieve full close-off pressure in dead-end service applications.
