Resideo VCZAS1100 Valve

The Resideo VCZAS1100 Valve is a professional-grade 1-inch sweat zone valve designed for precision in high-demand hydronic environments. This two-way cartridge cage valve features a 6.6 Cv rating and a linear flow profile, making it the standard choice for balancing domestic and light commercial heating and cooling systems. Built with a rugged bronze body and a stainless steel stem, the assembly provides a reliable 60 psi close-off pressure rating, ensuring consistent performance in both chilled and hot water applications. High-performance EPDM O-ring seals allow for compatibility with glycol concentrations up to 60%, maintaining structural integrity in low-temperature loops.

Designed for field efficiency, the VCZAS1100 utilizes a quick-change cartridge design, allowing technicians to rebuild the valve to factory specifications without removing the valve body from the line. This unit is fully compatible with any on/off VC style actuator, utilizing a head installation process that does not require system draining. Whether you are managing individual fan coils, baseboard radiators, or complex zone control arrays, this Resideo VC series valve delivers the durable flow control required by veteran mechanical contractors.

• High Close-Off Performance: Provides 60 psi differential pressure rating, independent of the Cv value, to prevent bypass and leakage.
• Hydronic Versatility: Engineered for chilled or hot water systems with high glycol tolerance (up to 60%) for diverse climate applications.
• Serviceable Design: Features a replaceable internal cartridge and a stainless steel stem for extended service life in demanding zone control systems.
• Efficient Installation: 1" sweat connection and a tool-free actuator mounting system reduce labor time on the job site.

Common Questions

Is the actuator included with this valve body?
No, this is the valve body and internal cartridge only. It is designed for use with Resideo/Honeywell VC series on/off actuators, which must be sourced separately.

Can I replace the internal components without cutting the pipe?
Yes. The Resideo VCZAS1100 is designed so the cartridge can be replaced using the included wrench, allowing a complete rebuild without removing the bronze housing or draining the entire loop if isolated.

What is the maximum fluid temperature this valve can handle?
This valve is rated for fluid temperatures ranging from 34°F to 203°F (1°C to 95°C), covering the vast majority of standard HVACR hydronic specifications.
