Erie By Schneider Electric VM3211P33A000 PopTop 3-Way Proportional Valve Assembly 1/2" Sweat

The Erie by Schneider Electric VM3211P33A000 is a complete PopTop modulating valve assembly designed for precise control in HVAC hydronic heating and cooling systems. This 3-way mixing valve features a 1/2-inch sweat connection and comes equipped with a proportional non-spring return actuator for accurate flow control.

Key Features:

• 1/2-inch sweat (solder) connection for easy installation
• 3-way mixing valve configuration with 1.0 Cv flow coefficient
• 50 PSI close-off pressure rating
• 24 VAC proportional actuator with 0-10 VDC or 4-20 mA control signal
• Non-spring return (NSR) design - fails in place on power loss
• Forged brass body with nickel-plated stem
• High-temperature thermoplastic plug and paddle
• ANSI Class IV seat leakage rating (0.01%)
• Tool-less actuator connection for quick installation
• Equal percentage flow characteristic

Technical Specifications:

• Service: Hot and chilled water, up to 50% glycol
• Operating temperature range: 32°F to 125°F (0°C to 52°C)
• System static pressure limit: 300 PSI
• Control signal: Proportional (0-10 VDC or 4-20 mA)
• Power requirements: 24 VAC
• NEMA 1 protection rating
• Rotary mechanical movement

The PopTop design allows the actuator to be installed after the valve body is already soldered into the system, simplifying installation in tight spaces. The proportional control provides precise modulating action for superior temperature control in zone valves, fan coils, baseboards, and air handlers.
