Erie By Schneider Electric VS3343 3/4" Inverted Flare 3-Way Zone Valve Body 4.0 Cv

The Erie VS3343 is a two-position zone valve body designed for low-pressure steam service applications, part of the PopTop Series that provides easy installation for heating systems. This valve features a 3/4" inverted flare (retrofit) connection with a 4.0 Cv flow coefficient, making it ideal for three-way mixing and diverting applications in HVAC systems.

Key Features:

• Forged brass body construction with nickel-plated stem and brass seat
• Highly saturated nitrile paddle designed for steam service
• Rated for steam applications up to 15 psi with compatible high-temperature actuator
• 400 psi static pressure rating for reliable performance
• ANSI class IV seat leakage rating (0.01%)
• Actuator can be installed after valve body is mounted to equipment
• Equal percentage flow characteristic for 1.0 to 4.0 Cv valves

The VS3343 valve body is part of the PopTop Series, featuring removable actuator compatibility with Erie AG (General Close-Off) or AH (High Close-Off) actuators. The valve body is compatible with spring return operation for fail-safe control and can be installed without special tools or calibration. The inverted flare connection design allows for retrofit installations in existing systems.

Note: This is a valve body only. Actuator and inverted flare fittings must be ordered separately. For steam applications, both valve body and actuator must be rated for high-temperature service.
