Resideo VCZML7100 Valve

The Resideo VCZML7100 is an industry-standard 3/4 inch sweat three-way cartridge cage valve engineered for precision flow control in commercial hydronic systems. Designed for proportional non-fail safe control using VC series actuators, this valve utilizes a stem up to close A port configuration. With a robust 6.6 Cv rating and a 60 psi close-off pressure, it provides reliable performance in both chilled and hot water applications, including systems containing up to 60% glycol concentration. The construction features a durable bronze body, a stainless steel stem, and high-grade EPDM O-ring seals to ensure long-term seat integrity and prevent bypass leakage during high-demand cycles.

Technical Specifications & Performance Benefits

• Optimized Flow Control: The high-flow 6.6 Cv capacity is balanced for hydronic mixing or diverting applications in fan coil and baseboard systems.
• Internal Durability: Engineered with a linear flow characteristic to prevent water hammer and provide stable modulation under varying pressure differentials.
• Contractor-Friendly Installation: The 3/4" sweat connection and field-replaceable cartridge design allow for rapid maintenance without breaking pipe connections.
• Material Compatibility: The EPDM seals and stainless steel internal components are specifically rated for treated water systems and high glycol mixes.

Common Installation & Compatibility Questions

Which actuators are compatible with the VCZML7100?
This valve body is designed specifically for Resideo VC series actuators, specifically those requiring proportional control and a non-fail safe (stay-in-place) operation.

Can this valve be used for steam applications?
No, this unit is rated for chilled or hot water systems only. Using this valve in steam environments will result in premature seal failure and potential system damage.

Is the cartridge replaceable?
Yes, the cartridge cage valve design allows for the internal assembly to be replaced using a 40007029-002 wrench without removing the bronze body from the line.
