Erie By Schneider Electric VM2323T33A000 NPT Modulating Zone Valve Assembly HVAC Control Valves & Actuators - 3/4 2-Way

The Erie by Schneider Electric VM2323T33A000 is a complete PopTop modulating zone valve assembly designed for precise control of hot and chilled water in HVAC applications. This assembly combines a 3/4-inch NPT brass valve body with a 24VAC floating control actuator, providing reliable modulating control without spring return for heating and cooling systems.

Key Features:

• 3/4-inch NPT threaded brass valve body with 2-way configuration
• Floating control actuator with non-spring return (NSR) operation
• Maximum operating pressure: 35 PSI differential
• Flow coefficient (Cv): 4.0 for optimal system performance
• 24VAC operation with no factory-installed leads
• Accepts 0-10 VDC or 4-20 mA control signals for modulating applications
• Forged brass body construction with nickel-plated stem
• NEMA 1 enclosure rating for indoor installations
• Temperature range: 32°F to 250°F fluid at 169°F ambient
• PopTop design allows actuator installation after valve body mounting

The PopTop modulating valve features a unique snap-on actuator design that mounts directly to the valve body without linkages or calibration, simplifying installation and service. The floating control actuator responds to raise/lower signals from compatible controllers, making it ideal for zone control in hydronic heating and cooling systems. The non-spring return feature maintains valve position during power loss, providing energy-efficient operation for continuously controlled applications.
