Schneider Electric (Erie) VM2221 Valve Body

When you're outfitting a hydronic system that demands precision, the Schneider Electric (Erie) VM2221 Valve Body is a standard for professional reliability. This 1/2-inch 2-way NPT zone valve is engineered for modulating service in hot and chilled water applications, featuring a 1.0 Cv rating that ensures stable flow control. Built with a rugged 300 psig rated forged brass body, it utilizes the Erie PopTop mounting system, allowing for one-handed actuator installation or removal without tools or complex linkages. This modulating valve body provides an equal percentage flow characteristic, which is critical for maintaining linear heat output in terminal units like fan coils and baseboards. Designed for seamless integration with Erie VM series actuators, the VM2221 handles media temperatures from 32° to 200°F and is compatible with up to 60% glycol solutions. For technicians, this means a Schneider Electric hydronic valve that minimizes labor time while delivering an ANSI Class IV leakage rating for superior close-off performance.

• Tool-Free Actuator Mounting: The PopTop design allows the motorized actuator to be snapped onto the brass zone valve body after piping, simplifying installation in tight mechanical spaces.
• High Static Pressure Rating: Rated for up to 300 psig, providing a robust solution for high-rise or large-scale commercial hydronic loops.
• Precise Flow Control: The 1.0 Cv rating and equal percentage characteristic prevent hunting and provide stable temperature regulation in HVAC modulation tasks.
• Durable Construction: Features a chrome-plated brass stem and high-temperature thermoplastic plug to prevent scale buildup and maintain a tight seal.

Is the VM2221 suitable for steam applications?
No, this specific model is designed for water and glycol mixtures only. It is not rated for steam service.

What actuators are compatible with this valve body?
The VM2221 is designed for use with Erie VM series modulating actuators, including both tri-state (floating) and proportional (0-10 VDC or 4-20 mA) models.

Can I install this valve in any orientation?
It can be mounted in horizontal or vertical piping. However, it is a professional best practice to avoid mounting the actuator below the valve body to prevent moisture or condensation from entering the housing.
