Resideo VC6934ZZ31 Floating Actuator

The Resideo VC6934ZZ31 Floating Actuator is a field-proven 24 Vac direct-coupled motor designed for precise proportional control in hydronic systems. Built for seamless integration with Honeywell VC Series valve bodies, this SP3T tri-state actuator provides dependable performance for central heating, fan coil units, and convectors. With a 0.4-inch stroke and a self-alignment shaft adapter, the VC6934ZZ31 ensures consistent seating and simplifies the installation process for technicians. It features a fails-in-place design, maintaining the last valve position during a power loss to prevent system swings. This double-insulated unit includes a 5-foot plenum-rated cable and a 3/8-inch flexible conduit adapter, making it ideal for tight mechanical spaces. Capable of handling a differential pressure of 60 psi and fluid temperatures up to 203°F, this replacement valve actuator is a standard for professional contractors seeking to maintain high-efficiency hydronic loops without draining the system during head replacement.

• Universal VC Compatibility: Engineered specifically for use with 2-way and 3-way Honeywell VC series valves, ensuring a perfect mechanical fit every time.
• Streamlined Installation: Features a self-aligning shaft adapter and quick-mount head that allows for service or replacement without draining the system.
• Robust Environmental Rating: IP40-rated plastic housing and conformal coated circuitry provide superior resistance to humidity (5-95% RH) and ambient temperatures up to 150°F.
• Efficient Power Consumption: Consumes only 6 VA while driving and utilizes an internal switching mechanism to draw power only when repositioning the valve.

Does this actuator require a specific control signal?
Yes, the VC6934ZZ31 is designed for 24 Vac SPDT or SP3T floating control signals. It is ideal for modulating applications where precise positioning is required from a 3-wire controller.

Can I replace the actuator head without shutting down the loop?
Correct. The VC series actuator design allows the head to be removed and replaced without breaking the plumbing seal or draining the hydronic system, significantly reducing labor time.

What is the close-off pressure rating?
When paired with compatible VC series valve bodies, this actuator provides a secure 60 psi close-off, preventing bypass and ensuring system integrity in high-demand residential or commercial applications.
