Schneider Electric (Erie) VM3312P33A000 Valve Assembly

The Schneider Electric (Erie) VM3312P33A000 is an industrial-grade 3-way modulating zone valve engineered for precision flow control in closed hydronic systems. This non-spring return (NSR) assembly features a 3/4 inch sweat connection and a 2.0 Cv flow coefficient, making it a reliable solution for fan coil units, VAV reheat coils, and radiant heating loops. Designed for 24Vac operation, the actuator is highly versatile, supporting multiple control signals including 0-10Vdc, 4-20mA proportional, and various voltage ranges (0-5Vdc, 5-10Vdc) to ensure seamless integration with modern Building Automation Systems (BAS).

Built with the iconic PopTop actuator design, this Erie zone valve assembly allows for tool-free installation and removal, facilitating rapid field service and reducing labor time for contractors. The valve body is constructed from forged brass with a high-temperature thermoplastic pop-top, capable of handling 300 psi static pressure and a close-off pressure of 50 psi. By utilizing a magnetic clutch, the motor and gear train are protected from excessive wear, ensuring consistent performance in demanding high-duty cycle applications. The 3-way mixing or diverting configuration provides the flexibility needed for sophisticated hydronic balancing.

Key Benefits

• Universal Compatibility: Accepts 0-10Vdc, 4-20mA, or 0-5Vdc signals for flexible modulating control without needing multiple actuator types.
• Contractor-Friendly Installation: The PopTop quick-release mechanism allows the actuator to be snapped into place without the need for complex linkages or calibration.
• Precision Fluid Control: Features an equal percentage flow characteristic for stable temperature regulation in HVAC zones.
• Durable Construction: The forged brass body and nickel-plated brass stem offer superior corrosion resistance and a long service life in closed-loop systems.
• High Close-Off: Rated for 50 psi close-off, preventing unwanted bypass and ensuring system efficiency.

Common Questions

Can this valve be used for both mixing and diverting applications?
Yes, the VM3312P33A000 is a 3-way valve designed for versatility in hydronic piping, though 3-way valves are typically configured for normally closed operation on the B-port.

Does this valve require a specific mounting orientation?
For optimal performance, the valve should be mounted where the actuator is above the horizontal plane of the piping to prevent condensate or debris from entering the motor housing.

Is the actuator field-replaceable without draining the system?
Yes, the PopTop design permits the actuator to be removed or replaced without breaking the plumbing line or draining the hydronic loop.
