Resideo VCZAR1100 Valve

The Resideo VCZAR1100 is an industrial-grade 1-inch NPT two-way cartridge cage valve engineered for precision control in hydronic systems. Designed with a 6.6 Cv flow coefficient and a linear flow characteristic, this valve ensures stable temperature regulation in both chilled and hot water applications. The bronze body construction, paired with a stainless steel stem and EPDM O-ring seals, provides the durability required for closed-loop systems containing up to 60% glycol concentration. This unit handles a 60 psi close-off pressure, effectively preventing leakage and ghost flow when paired with a compatible VC style on/off actuator. The cartridge cage design allows for rapid internal component replacement without breaking pipe connections, a critical feature for minimizing downtime during mechanical room maintenance. Whether you are balancing a commercial air handler or managing a multi-zone residential loop, the VCZAR1100 delivers the hydraulic performance and pressure-balanced operation expected in high-demand HVACR environments.

• Field-Replaceable Cartridge: The Resideo VC Series valve architecture allows for internal repairs without system drainage or pipe removal.
• High Glycol Tolerance: Compatible with up to 60% glycol, making it ideal for hydronic heating and cooling loops in cold climates.
• Corrosion Resistance: Features a rugged bronze valve body and stainless steel trim to withstand aggressive water chemistry.
• Reliable Close-off: Engineered for 60 psi close-off to eliminate bypass flow and improve system efficiency.
• Versatile Compatibility: Seamlessly integrates with Resideo VC actuators for simplified on/off control logic.

Is the VCZAR1100 suitable for steam applications?
No, this Resideo zone valve is strictly rated for chilled and hot water applications. Using it with steam will compromise the EPDM seals and lead to premature failure.

Can I use a modulating actuator with this valve?
While the VCZAR1100 2-way valve features a linear flow stroke, it is primarily optimized for use with on/off VC style actuators. For modulating requirements, verify the specific actuator stroke timing and signal compatibility.

What is the benefit of the linear flow characteristic in this valve?
The linear flow valve design ensures that the flow rate is directly proportional to the position of the stem, providing predictable performance in hydronic control systems.
