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

Smith 100187880 part ensures a perfect fit without field modifications

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

If the pressure exceeds the high-limit threshold

Resideo VC7934ZZ31 Modulating Actuator 320074-702 The assembly is designed forThe 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
