Erie By Schneider Electric VM3222T33A00T PopTop 3-Way Mixing Zone Valve Assembly 1/2" NPT

The Erie By Schneider Electric VM3222T33A00T is a PopTop Series modulating zone valve assembly designed for precise control in hydronic heating and cooling systems. This complete assembly combines a 3-way mixing valve body with a floating control actuator, providing tool-less installation and easy field serviceability.

Valve Body Specifications (VM3222):

• Configuration: 3-way mixing valve for blending applications
• Connection Size: 1/2" NPT threaded connections
• Flow Coefficient: 2.0 Cv with equal percentage flow characteristic
• Close-Off Pressure: 50 PSI maximum differential pressure
• Body Material: Forged brass construction with nickel-plated stem
• Static Pressure Rating: 300 PSI maximum system pressure
• Service Media: Hot and chilled water, glycol solutions (25-60%)
• Temperature Range: 32°F to 200°F fluid temperature (not steam rated)

Actuator Specifications (AT33A000):

• Control Type: Floating control with 3-wire signal input
• Power Supply: 24 VAC at 50/60 Hz
• Operation: Non-spring return (NSR) with fail-in-place positioning
• Includes Time-Out: Built-in 3-minute time-out logic for precise positioning
• Lead Configuration: No factory-installed leads for field wiring flexibility
• Power Consumption: 1.2 VA during operation
• Operating Temperature: 35°F to 125°F ambient temperature range
• Enclosure Rating: NEMA 1 / IP10 protection
• Features: Magnetic clutch for extended motor life, manual operating lever with position indicator

Installation Benefits: The PopTop design allows the actuator to be installed after the valve body has been mounted to the system, eliminating the need for valve removal during actuator replacement. No linkages or calibration required—the actuator simply snaps onto the valve body. Manual override lever facilitates commissioning and troubleshooting.

Ideal for fan coils, baseboards, air handlers, and radiant heating systems requiring modulating control. UL Listed and cUL Listed for use in the United States and Canada.
