Schneider Electric (Erie) VM3312T33A000 Valve Assembly
The Schneider Electric Erie VM3312T33A000 is an industrial-grade 3-way zone valve assembly engineered for precise fluid control in closed-loop hydronic systems. This PopTop series valve features a 3/4-inch sweat connection and is designed for mixing applications in fan coils, VAV reheat units, and radiant heating setups. Operating on 24Vac, the high-torque actuator utilizes a three-wire floating signal (tri-state) for incremental positioning without a spring return mechanism. This non-spring return zone valve provides a 2.0 Cv flow coefficient, ensuring an equal percentage flow characteristic for stable modulated control of hot or chilled water and glycol solutions up to 60% concentration.
The VM3312T33A000 valve assembly is built with a forged brass body and a high-temperature thermoplastic plug, rated for static pressures up to 300 psi and a 50 psi close-off differential. The PopTop actuator allows for one-handed removal, simplifying field service and replacement. For contractors, the direct-acting VM3312T33A000 provides a reliable solution for precise temperature maintenance in multi-zone hvac applications.
Key Benefits- Syncro-Motor technology: The 24V floating actuator provides consistent timing and positioning for accurate flow modulation.
- Serviceable Design: The PopTop quick-release actuator snaps directly onto the brass valve body, eliminating the need for complex linkages.
- High Close-Off Performance: Maintains system integrity with a 50 psi differential pressure rating, preventing leakage in high-head applications.
- Manual Override: Includes a manual lever to position the valve during startup or system maintenance.
Is the VM3312T33A000 suitable for steam applications?
No, this 3-way sweat zone valve is rated for water and glycol solutions up to 200°F and should not be used in steam systems.
What is the difference between this and a spring return model?
This non-spring return valve remains in its last position upon loss of power, whereas spring-return models use a mechanical spring to fail-safe to a specific port.
How do I wire this three-wire floating valve?
The actuator uses a common wire, an "open" signal wire, and a "close" signal wire. The controller must provide a tri-state signal to drive the motor in either direction.
