Resideo VCZAL3400 Valve

The Resideo VCZAL3400 Valve is a professional-grade 3/4 inch NPT 2-way cartridge cage valve designed for precision in modern hydronic systems. Engineered for high-performance zone control, this bronze body valve handles both chilled and hot water applications, including high-concentration glycol solutions up to 60%. With a 3.9 Cv rating and an equal percentage flow characteristic, it ensures linear control when paired with proportional non-fail safe VC style actuators.

This hydronic zone valve is built for reliability in demanding environments, featuring a stainless steel stem and durable EPDM O-ring seals. The balanced cartridge cage design provides a formidable 60 psi close-off pressure, ensuring tight shut-off regardless of system pressure fluctuations. Designed for the field, the unique twist-lock mounting allows for actuator removal without draining the system, or tools, significantly reducing labor time during maintenance or cartridge replacement.

• Efficient Maintenance: The replaceable valve cartridge design allows you to rebuild the valve to factory-new condition without removing the bronze body from the pipeline.
• High Close-Off Capacity: Rated for 60# close-off pressure, providing reliable performance in high-head pumping systems.
• Versatile Media Compatibility: Suitable for hydronic systems utilizing up to 60% glycol, ideal for commercial or residential chilled water setups.
• Rapid Actuator Swaps: Compatible with 3000-series modulating actuators; the twist-lock mechanism ensures no-tool installation and service.

• Is this valve bi-directional? Yes, the Resideo VCZAL3400 is designed for bi-directional flow, simplifying installation in tight mechanical headers.
• Do I need to drain the loop to replace the actuator? No, current VC series designs allow for head removal while the system is fully pressurized.
• What actuators are compatible with this body? This specific body is intended for use with proportional (modulating) VC style actuators that are non-fail safe.
