Product Description

The RESIDEO VCZAL1100/U is a 2-port VC valve body designed for domestic and small commercial heating and cooling applications, specifically for zone control. This balanced 2-position hydronic valve controls the flow of hot and/or cold water and can be combined with any VC series On/Off actuator. It features a rugged design, high pressure differential up to 4 bar, and high flow rate capacity. The valve housing is made of bronze, and the cartridge is made of Ryton and Noryl plastic with a stainless steel spindle.

• Quick open, linear, and equal percentage flow characteristics are available.
• Bi-directional installation is supported.
• Actuator installation or removal requires no tools, and removal does not necessitate draining the system.

Product Highlights

This valve offers a 10-year operational lifetime, with service achieved by replacing the cartridge, which rebuilds the valve to factory-new condition. It is CSA Certified and compatible with cold, warm, and hot water applications, including up to 60% glycol mixtures.
