Schneider Electric (Erie) VM3323 Valve Body

The Schneider Electric Erie VM3323 is a high-performance 3-way modulating zone valve body engineered for precision flow control in closed hydronic systems. Featuring a 3/4" NPT connection and a robust 4.0 Cv rating, this brass zone valve is an industry standard for managing hot and chilled water applications, including fan coils and radiant manifolds. Designed for the Erie PopTop series, the VM3323 utilizes a paddle-style design that ensures an ANSI Class IV seat leakage rating, providing tight shut-off and reliable diversion or mixing. The forged brass body and stainless steel stem assembly are built to withstand high static pressures up to 300 PSI. This modulating valve body is compatible with proportional actuators (0-10 VDC or 4-20 mA) and three-wire floating actuators, allowing contractors to achieve exact temperature stabilization without the hunting common in lower-quality alternatives. Its equal percentage flow characteristic ensures linear heat output, making it the preferred choice for sophisticated building automation systems (BAS).

• Interchangeable Actuator Design: The PopTop mounting allows for one-handed installation and removal, significantly reducing labor time during field service or replacement.
• Efficient Hydronic Balancing: A 4.0 Cv flow coefficient provides the necessary capacity for medium-sized residential and commercial zones while maintaining strict control over glycol-water mixtures.
• Superior Seating: Engineered with a high-temperature thermoplastic pop-top paddle to ensure minimal bypass and long-term reliability in varying thermal conditions.
• Versatile Application: Primarily used for mixing or diverting in HVAC setups, the VM3323 handles fluid temperatures ranging from 32°F to 200°F.

What is the maximum close-off pressure for the VM3323?
When paired with a standard non-spring return actuator, this valve typically manages a 35 PSI close-off pressure, ensuring reliable performance in most high-head circulating systems.

Is this valve body compatible with steam systems?
No, the VM3323 is specifically rated for hot and chilled water or glycol solutions up to 50%. It is not intended for use in steam applications.

Can I use this for both mixing and diverting?
Yes, the 3-way valve body design is suitable for both mixing and diverting configurations depending on the piping layout and actuator setup used in your hydronic loop.
