Erie By Schneider Electric VM3313P33A000 3/4" Modulating Zone Valve Assembly 3-Way Non-Spring Return

The Erie by Schneider Electric VM3313P33A000 is a complete 3/4-inch three-way modulating zone valve assembly designed for precise flow control in residential and commercial HVAC hydronic heating and cooling systems. This assembly combines a brass valve body with the AP33A000 proportional non-spring return actuator for accurate temperature zone control.

Valve Body Specifications:

• Size: 3/4 inch sweat (copper) connections
• Configuration: 3-way mixing valve for zone applications
• Flow coefficient: 4.0 Cv with equal percentage flow characteristic
• Close-off pressure rating: 35 PSI
• Forged brass body with chrome-plated brass stem and brass seat
• Operating fluid temperature range: 32°F to 200°F (not rated for steam)
• Compatible with water and glycol mixtures (25-60%)
• Static pressure limit: 400 PSI

AP33A000 Actuator Features:

• 24 VAC power input (+25%/-15%, 50/60 Hz)
• Proportional modulating control with selectable signal ranges: 0-10 VDC, 0-5 VDC, 5-10 VDC, or 4-20 mA
• Non-spring return (NSR) operation - maintains position on power loss
• Direct acting with field-selectable reverse acting capability
• Low power consumption: 1.7 VA running, 10 VA inrush
• Manual override lever for manual positioning
• High-temperature plastic housing rated for 35°F to 125°F ambient
• NEMA Type 1 enclosure, UL and cUL listed

PopTop Design Benefits:

The Erie PopTop series allows the actuator to mount directly onto the valve body without linkages or calibration, enabling quick installation and easy field servicing. The valve can be mounted in horizontal or vertical piping, with the actuator positioned above the valve body when installed horizontally.

Typical Applications:

Ideal for hydronic heating systems, chilled water cooling systems, radiant floor heating, and multi-zone HVAC control where proportional modulating control is required for optimal comfort and energy efficiency.
