Schneider Electric (Erie) VT2221G23A020 Valve Assembly
The Schneider Electric (Erie) VT2221G23A020 Valve Assembly is a heavy-duty 2-way normally open zone valve engineered for precision fluid control in hydronic heating and cooling systems. Built around the industry-standard Erie PopTop platform, this assembly features a 1/2" NPT threaded connection and a 1.0 Cv flow coefficient, making it ideal for high-head fan coil and baseboard applications. The unit operates on a 24Vac power supply and utilizes a spring return mechanism to ensure a fail-safe position during power loss. Its synchronous motor-driven actuator is designed for high-cycle reliability and can be removed from the forged brass valve body with a single button press—no tools required. This two-position zone valve supports a maximum static pressure of 400 psi and close-off pressure ratings optimized for commercial and residential hydronic loops, ensuring tight shut-off and preventing leakage in multi-zone configurations.
Key Benefits- Tool-less Actuator Removal: The iconic PopTop design allows you to snap the actuator on or off for quick maintenance without breaking the line.
- Fail-Safe Operation: Mechanical spring return ensures the valve defaults to the open position if the 24V signal is lost.
- High-Pressure Capability: Built with a forged brass body and nickel-plated stem rated for 400 psi system pressure.
- Direct Replacement: Fits existing Erie valve footprints, simplifying retrofits for fan coil and air handler units.
- Durable Motor: Use of a hysteresis synchronous motor extends the service life in demanding HVAC environments.
Can I use this valve for low-pressure steam applications?
No, the VT series uses a Buna-N paddle suitable for water and glycol up to 50%. For steam applications, the VS series (High Temperature) must be specified.
Does this assembly include an auxiliary end switch?
The VT2221G23A020 model is a standard two-wire configuration. If you require a dry contact for pump or boiler sequencing, verify the specific model dash code for end-switch integration.
What is the maximum fluid temperature for this valve?
The standard VT assembly is rated for fluid temperatures up to 200°F (93°C), provided the ambient temperature at the actuator remains within operational limits.
