Erie By Schneider Electric VM3312T33A00T 3/4" Sweat 3-Way Zone Valve 50 PSI 24VAC Floating Non-Spring Return

The Erie By Schneider Electric VM3312T33A00T is a PopTop modulating zone valve assembly designed for reliable hydronic heating and cooling system control. This 3-way mixing valve features a 3/4-inch sweat connection and is engineered for easy installation and maintenance in residential and commercial HVAC applications.

Key Features:

• 3/4-inch sweat (solder) connection for secure, leak-free installation
• 3-way mixing configuration for versatile system design
• 50 PSI maximum working pressure rating
• 24VAC power supply with three-wire floating control signal
• Non-spring return (NSR) operation for maintained position control
• Includes time-out feature for enhanced control precision
• NEMA 1 enclosure rating for indoor applications
• Forged brass body construction rated for 300 PSIG durability
• One-handed actuator removal for simplified servicing
• No linkages or calibration required for installation

The PopTop series design allows the actuator to be easily attached or removed with one hand after the valve body has been installed into the system. The floating non-spring return actuator maintains its position when de-energized, providing precise control for glycol and water systems. The valve plug is constructed from high-temperature thermoplastic material, and the brass stem is nickel-plated for corrosion resistance and long service life.

This valve assembly is ideal for zone control applications in hydronic heating systems, radiant floor heating, and chilled water cooling systems where reliable, low-maintenance operation is essential.
