Resideo VC7934ZZ11 Modulating Actuator
The Resideo VC7934ZZ11 Modulating Actuator is a professional-grade solution for precise fluid control in hydronic systems, including fan coils, radiators, and convectors. Operating on 24 Vac power, this direct coupled actuator utilizes a 2-10 Vdc control signal to provide linear flow characteristics and accurate positioning. Built for high-demand environments, it handles a 60 psi maximum differential pressure for reliable close-off performance.
Designed for streamlined field service, the Resideo VC7934ZZ11 features a self-aligning shaft adapter and a 5-foot plenum-rated cable for versatile installation. This model is engineered to fail in place upon loss of power, maintaining the current valve position to prevent system shocks. With its non-spring return motor and 120-second stroke timing, it ensures quiet, stable modulation without the abrupt hunting often seen in lower-quality substitutes. It is compatible with Resideo 1000, 2000, and 3000 series 2-way and 3-way valve bodies, providing a 300 psi static pressure rating for robust HVAC applications.
Key Benefits- High Close-off Reliability: Rated for 60 psi close-off to ensure zero leakage in high-head pressure systems.
- Simplified Maintenance: The manual override lever and twist-lock mounting allow for actuator head replacement without draining the loop.
- Universal Compatibility: Seamlessly integrates with building automation systems (BAS) and DDC controllers via standard proportional control signals.
- Durable Construction: Features a double-insulated housing and flexible conduit adapter for safe, code-compliant wiring in plenum spaces.
- Does this actuator return to a home position during power loss? No, the VC7934ZZ11 is a fail-in-place model, meaning it maintains its last commanded position if 24V power is interrupted.
- Can I use this for both mixing and diverting applications? Yes, when paired with the appropriate Resideo VC series 3-way valve body, it supports both mixing and diverting flow patterns.
- Is a separate transformer required? This unit requires a 24 Vac Class 2 power supply (6 VA driving), typical for most HVAC zone control circuits.
