Schneider Electric (Erie) VT3323 Valve Body

The Schneider Electric (Erie) VT3323 is a high-performance 3-way zone valve body engineered for demanding hydronic heating and cooling systems. Built with a rugged forged brass body and a nickel-plated stem, this 3/4-inch NPT valve provides a 4.0 Cv flow coefficient, ensuring efficient fluid regulation in fan coil units, baseboards, and air handlers. As part of the Erie PopTop series, this component is designed for seamless integration with two-position spring return actuators, allowing for tool-free installation and maintenance after the body is piped into the system.

The VT3323 valve body is rated for a static pressure of 400 psi and can handle media temperatures up to 200°F (93°C), making it a versatile choice for both chilled water and hot water applications, including 50% glycol mixtures. Its mixing and diverting configuration provides technicians with flexible piping options to meet specific zone requirements. This PopTop zone valve serves as a direct, drop-in replacement for existing Erie legacy applications, ensuring long-term reliability without the need for complex recalibration or linkage adjustments.

Key Benefits

• Fast Installation: The PopTop design allows actuators to snap onto the VT3323 body without tools, reducing labor time on the job site.
• High Durability: Constructed with a forged brass body and BUNA N paddle to withstand high static pressures and repeat cycling.
• System Flexibility: Functional for both mixing and diverting applications in closed hydronic loops.
• Low Maintenance: Stainless steel base plate and corrosion-resistant materials ensure consistent two-position control performance.

Common Questions

What is the maximum pressure rating for the VT3323?
The Schneider Electric VT3323 is rated for a 400 psi static pressure and 300 psi operating pressure, suitable for high-rise or commercial hydronic configurations.

Can I use this valve for steam applications?
While the VT series is designed primarily for water and glycol, the standard VT3323 is rated for 15 psig low-pressure steam when paired with specific high-temperature actuators.

Is the actuator included with this model?
No, the VT3323 is the 3-way valve body only. It must be paired with an Erie PopTop actuator (AG or AH series) to function as a complete zone control valve.
