Erie By Schneider Electric VM3323T33A00T NPT Modulating Zone Valve Assembly HVAC Control Valves & Actuators - 3/4 3-Way

The Erie By Schneider Electric VM3323T33A00T is a 3/4-inch NPT three-way PopTop modulating zone valve assembly designed for precise control in hydronic heating and cooling systems. This valve features a 4.0 Cv flow rating and threaded NPT connection, making it suitable for a variety of HVAC applications including fan coil units, VAV reheat, unit ventilators, and air handling units.

Key Features:

• PopTop floating zone valve assembly with 3-wire, non-spring return design for modulating control from a floating (raise/lower) controller signal
• 24 VAC operation with built-in time-out feature
• Rugged 300 PSIG rated brass forged body design for long life
• One-handed engagement or removal of the motorized actuator to the valve body
• Valve actuator can be easily attached after the valve body has been installed into the system without the need of linkages or calibration
• Three-way VM valves must be piped in a mixing configuration, not diverting
• The Modulating PopTop Series valves require no maintenance

These valves are designed for application to closed hydronic heating and cooling systems and are not recommended for use in systems which have substantial make-up water (open systems), as high levels of dissolved oxygen, chlorine, and debris can attack valve materials. The valve can be mounted in horizontal or vertical piping, with the actuator positioned above the valve body when installed horizontally. The 35 PSI rating and floating control make this valve ideal for precise temperature control in commercial and residential HVAC applications.
