Installation Instructions PDF ↗

The VCZAL3100 is a VC series two-way valve assembly from Resideo, the brand that carries the Honeywell Home line of residential heating controls, built for hydronic zoning and fan coil control. It is a 3/4-inch female NPT body with a 4.7 Cv rating and a linear flow characteristic.

A linear characteristic means flow tracks stem position in a straight line, which keeps a modulating loop stable instead of dumping most of its capacity in the first part of the stroke.

What a complete VC zone valve takes: a valve body, a cartridge, and an actuator, ordered separately. This listing is the valve assembly — pick the actuator that matches your control signal, whether that is two-position, floating, or modulating.

Building the valve from separate parts is what makes the VC platform worth specifying: the same body stays in the pipe while the actuator is matched to the control system, and a worn seat is handled by pulling the cartridge rather than cutting the body out.
