Schneider Electric (Erie) VM3211T33A000 Valve Assembly

The Schneider Electric (Erie) VM3211T33A000 is an industrial-grade three-way mixing valve assembly designed for precise hydronic control in fan coil, baseboard, and VAV reheat applications. Built on the Erie PopTop platform, this assembly features a 1/2 inch sweat connection and a forged brass body rated for 300 psig static pressure. The non-spring return zone valve utilizes a 24Vac synchronous motor to provide a three-wire floating signal, ensuring the valve remains in its last position upon loss of power. With a 1.0 Cv flow coefficient and a patented equal percentage flow plug, technicians can maintain stable discharge temperatures in closed-loop systems. The tool-less actuator connection simplifies field service, while the ANSI Class IV seat leakage rating and 50 PSI close-off pressure ensure reliable shut-off performance. This VM3211T33A000 Valve Assembly is suitable for water and glycol solutions (up to 60%) but is not rated for steam use.

• Floating Control Precision: Synchronous motor driving a 24Vac three-wire signal for accurate positioning without the snap-back of spring return models.
• Rugged Build Quality: High-temperature thermoplastic actuator housing paired with a forged brass 1/2" sweat valve body for long-term durability.
• Service-Friendly Design: The Erie PopTop series allows for a tool-less actuator release, significantly reducing labor time during maintenance or replacement.
• Superior Flow Characteristics: Designed with an equal percentage flow plug to optimize heat transfer across a wide range of hydronic demands.

Is the VM3211T33A000 suitable for steam applications?
No, this assembly is strictly for chilled or hot water and glycol mixtures. Using this valve with steam will damage the internal paddle and seals.

What happens if the power is cut to this non-spring return valve?
As a non-spring return zone valve, it will "fail in place," maintaining its current position until power is restored and a new signal is received.

Can I use this for a diverting application?
This specific configuration is designed for three-way mixing. For proper operation and to avoid water hammer or chatter, it must be piped so that the flow enters from the two inlet ports and exits through the common port.
