The Erie By Schneider Electric VS2222H24A020 is a complete two-position spring return zone valve assembly designed for controlling flow in hydronic heating systems and steam applications. This PopTop series valve features a normally open configuration with high temperature rating, making it suitable for demanding HVAC applications including steam service up to 15 PSI.

Key Features:

• 1/2 inch NPT threaded connection for easy installation
• 2-way valve configuration for on/off zone control
• 50 PSI close-off pressure rating
• 24 VAC power supply at 50/60 Hz
• Normally open (N.O.) spring return actuator
• High temperature rated for steam and hot water applications
• Forged brass valve body with nickel-plated stem
• Highly saturated nitrile paddle for enhanced durability
• ANSI Class IV seat leakage rating (0.01%)

This valve assembly is designed for use in closed hydronic heating and cooling systems, including applications with hot water and up to 50% glycol solutions. The high temperature rating allows operation with fluid temperatures from 32°F to 250°F at ambient temperatures up to 169°F. The spring return actuator provides fail-safe operation, automatically returning to the open position when power is removed. Installation can be in horizontal or vertical piping with the actuator mounted above the valve body. UL 873 listed and CSA certified for reliable performance in commercial and residential HVAC systems.
