Schneider Electric (Erie) VM3322 Valve Body

For veteran HVAC contractors managing hydronic systems, the Schneider Electric Erie VM3322 three-way zone valve body is a reliable solution for precision fluid control. This 3/4-inch NPT threaded valve features a 2.0 Cv flow coefficient, engineered specifically for mixing applications in fan coils, VAV reheat units, and baseboard heating. Constructed from high-quality forged brass with a thermoplastic plug and chrome-plated stem, this modulating valve body is rated up to 300 psig static pressure. It is fully compatible with the Erie PopTop actuator series, allowing for tool-free installation and removal with a simple snap-on mechanism. Designed for closed-loop hydronic heating and cooling, it supports water or glycol solutions up to 50% concentration within a temperature range of 32° to 200°F. The ANSI Class IV leakage rating ensures a tight shut-off, maintaining system efficiency and preventing ghost flows in complex residential or commercial heating zones.

• Precise Flow Control: The 2.0 Cv rating and equal percentage flow characteristics provide stable modulation and accurate temperature management in hydronic zones.
• Durable Construction: Forged brass body prevents corrosion and sustains a 300 psi maximum pressure rating for demanding mechanical room environments.
• Rapid Actuator Integration: The PopTop design enables contractors to mount or replace actuators without draining the system or using specialized tools.
• Universal Pipe Compatibility: Standard 3/4" FNPT connections facilitate seamless integration into existing threaded copper or iron pipe headers.
• System Reliability: Features a high-temperature thermoplastic plug and a robust seal to maintain long-term performance in varied fluid conditions.

Is the VM3322 suitable for steam applications?
No, this specific model is designed for hot and chilled water systems only. It is not rated for steam use.

What actuators are compatible with the VM3322 valve body?
This valve body is designed to pair with Schneider Electric Erie PopTop series actuators, specifically the AT (floating) and AP (proportional) modulating models.

Can this valve be used for both mixing and diverting?
The VM3322 is a three-way mixing valve. For diverting applications, ensure the high-pressure source is correctly piped to the common port to avoid chatter and seat damage.
