Resideo VC7934ZZ31 Modulating Valve Actuator 24VAC 0-10VDC/2-10VDC Control Signal Direct Coupled

The Resideo VC7934ZZ31 Modulating Actuator is a control device that controls the flow of water in HVAC systems. It is particularly intended for use with Resideo’s 3000 and 7000 series VC valves. When the actuator receives a (0)2-10 VDC control signal, the valve opening is accurately adjusted and this gives an accurate control of water temperature and flow rate. This modulating actuator is vital to enhancing system performance and energy efficiency. It makes possible gradual and sustainable adjustments to the valve, preventing cases of when the valve is adjusted in a way that could inconvenience for the valve owner or indeed destabilize the system.
