Key Benefits: Heavy-Duty Construction: Zinc die-cast housing provides superior protection against dust and mechanical impact compared to standard actuators

The assembly is designed for a 6-inch air tube length

Key Benefits for Technicians Enhanced System Reliability: The automatic reset functionality on both LP and HP stages reduces downtime by allowing the refrigeration system to resume operation once safe pressures are restored

Integrating this condenser fan blade replacement restores the factory-spec performance necessary for consistent cooling cycles

Resideo VC7934ZZ31 Modulating Actuator 320074-702 Key Benefits: Heavy-Duty Construction: ZincThe 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
