Resideo VC7934ZZ31 Modulating Actuator
The Resideo VC7934ZZ31 is a high-performance modulating valve actuator designed for precise flow control in commercial hydronic systems. Operating on a 24 Vac power supply, this unit utilizes a 0/2-10 Vdc control signal to provide linear positioning for VC series valves. Unlike spring-return models, this actuator fails in place upon loss of signal or power, maintaining the current valve position to prevent sudden system shifts. Engineering for high-pressure environments, it handles a 60 psi maximum differential pressure for reliable close-off in high-head applications. The direct coupled mounting design, paired with a self-aligning shaft adapter, ensures a secure mechanical connection and eliminates common installation alignment errors that lead to premature wear.
For serviceability and field installation, the VC7934ZZ31 features a manual operator lever to allow for manual override and valve positioning during commissioning or power outages. The 5-foot plenum rated cable simplifies wiring in air handling spaces, meeting strict fire safety codes for commercial configurations. This direct replacement actuator is compatible with all VC series 2-way and 3-way valve bodies, providing a versatile solution for balancing and temperature control loops where modulating accuracy is critical for system efficiency.
Key Benefits- Universal Compatibility: Fits all VC series valve bodies, providing a standardized low voltage actuator solution for mixed-valve inventories.
- Precise Modulation: Responds accurately to proportional control signals, ensuring stable discharge air temperatures and optimal heat transfer.
- Simple Mechanical Integration: The self-aligning shaft adapter reduces torque strain on the valve stem, extending the life of the mechanical assembly.
- Code Compliant Wiring: Integrated plenum rated cable eliminates the need for additional conduit in many drop-ceiling and air-return applications.
Can I use the VC7934ZZ31 to replace a 3-point floating actuator? No, this model is designed specifically for 0/2-10 Vdc modulating signals. If your controller outputs a floating or SPDT signal, you will need the VC6900 series.
Does this unit return to a closed position during a power failure? This is a non-spring return actuator that fails in place. If your application requires a fail-safe (open or closed) position, a spring-return model is necessary.
What is the purpose of the manual lever? The lever allows technicians to manually move the modulating control valve for flushing the system or testing flow without power or a control signal.
