"Our job is helping you do your job"
The VT Series Two-Position PopTop™ zone valves offer a wide range of models to handle chilled water, hot water, and 15 psig (103 kPa) steam applications. Each PopTop zone valve features a removable actuator to aid in both installation and service. The 2-way zone valve and 3-way zone valve are available in many body patterns and with normally open or normally closed actuators. This wide range of zone valves meets a variety of needs for Building Automation Systems, BAS, and HVAC/R applications.
