Schneider Electric (Erie) VT2221G13B020 Valve Assembly

The Schneider Electric Erie VT2221G13B020 is a commercial-grade two-way normally closed zone valve designed for precise hydronic control in HVAC systems. Engineered for high-cycle reliability, this 1/2" NPT zone valve features a 1.0 Cv flow coefficient, making it ideal for fan coil units and baseboard heating applications where moderate flow capacity is required. The 120V spring return actuator ensures a fail-safe closed position upon power loss, preventing unauthorized flow during system outages. This PopTop series valve utilizes a synchronous motor-driven actuator that can be replaced without draining the system, significantly reducing maintenance downtime for contractors. Built to handle fluid temperatures up to 200°F and static pressures up to 300 psi, this low-pressure steam and hot water valve provides tight shut-off and consistent performance in demanding multi-zone hydronic layouts. Its compact footprint allows for easy installation in tight mechanical headers and cabinet enclosures.

• Removable PopTop Actuator: Facilitates rapid motor replacement without breaking pipe seals or draining the loop.
• Spring Return Fail-Safe: Ensures the two-position valve returns to the normally closed state for system protection.
• Robust Environmental Rating: Designed to operate in high-humidity environments with a high-temperature bellows seal.
• Standardized 1/2" NPT Connections: Provides a secure, leak-proof interface with standard threaded copper or steel piping.

Can this valve be used in chilled water systems?
Yes, the VT2221G13B020 is compatible with chilled water, hot water, and low-pressure steam applications, provided the fluid temperature remains within the specified range.

What is the maximum differential pressure this valve can close against?
This specific 1.0 Cv model is engineered to provide a tight close-off against standard system pressures typically found in residential and light commercial zone control.

Does the actuator require a specific mounting orientation?
The valve should be mounted within 90 degrees of vertical; however, mounting it with the actuator upside down is not recommended to prevent condensate from entering the motor housing.
