Schneider Electric (Erie) VS3223 Valve Body

The Schneider Electric Erie VS3223 is a rugged 1/2 inch NPT three-way zone valve body designed for demanding hydronic and steam applications. Engineered for precise fluid control, this 4.0 Cv valve features a three-way divert configuration that ensures reliable flow management in low-pressure steam and liquid systems. Built for professional contractors, the VS3223 utilizes a two-position steam valve body architecture, allowing it to handle temperatures up to 250°F and line pressures up to 300 psi. Its nickel-plated brass construction and stainless steel stem provide superior resistance to scaling and corrosion, common issues found in aging piping networks. This Erie Pop-Top series component is fully compatible with AG and AH series actuators, enabling a quick-connect installation that reduces labor time on the job site. Whether you are performing a HVAC valve replacement or a new fan coil unit installation, this NPT threaded zone valve delivers the mechanical tolerances and flow coefficients required for balanced hydronic temperature control.

Key Benefits for Technicians

• High Flow Capacity: The 4.0 Cv rating ensures minimal pressure drop across 1/2" NPT connections.
• Universal Compatibility: Seamlessly integrates with Schneider Electric Pop-Top actuators for simplified maintenance.
• Durable Internals: Features a stainless steel stem and high-performance EPDM seals for extended valve life cycles.
• Steam Rated Performance: Specifically engineered as a steam-rated zone valve capable of handling 15 psi saturated steam.
• Compact Footprint: Designed for tight mechanical closets and HVAC terminal unit configurations.

Common Installation & Performance Questions

Can the VS3223 be used in both heating and cooling loops?
Yes, the VS3223 is suitable for chilled water systems and heating applications, provided the glycol concentration does not exceed 50% and temperature limits are maintained.

What is the maximum static pressure for this 3-way valve?
The Schneider Electric VS3223 is rated for a static pressure of 300 psi, making it ideal for high-rise hydronic distribution.

Is the actuator included with this valve body?
This is the valve body only. You must pair it with a compatible Erie Pop-Top spring return or non-spring return actuator to complete the assembly.
