The CC‑PCNT05 is a precision-proportional control actuator designed for modulating control in HVAC and hydronic systems. Unlike simple on/off actuators, this unit supports finer control with continuous positioning, ideal for advanced climate management and energy-efficiency systems.
It belongs to a line of advanced control actuators meant to deliver stable, accurate, and quiet modulation of valves in heating, cooling, and mixed systems. The “PCNT” in its name hints at Proportional / Continuous control.

The CC‑PCNT05 is a modulating actuator used to adjust valve opening continuously based on a control signal (e.g., 0–10 V). It translates analog control signals into mechanical displacement, modulating flow in hydronic circuits. It is engineered for quiet, smooth operation and integrates with controllers, thermostats, or building management systems (BMS).
Its internal mechanism includes a motor, gear train, position feedback sensor, and control electronics. As the control voltage varies, the actuator responds proportionally, positioning a valve stem or plunger to a corresponding opening. This enables fine-grained control of fluid flow, maintaining stable temperatures and higher comfort levels in heating/cooling zones.
HVAC zone control in commercial or residential buildings
Modulating control of underfloor heating circuits
Proportional control of radiator valves
Chilled ceiling / chilled beam systems
Variable flow fan-coil or hydronic terminal units
Integration in building automation systems (BAS/BMS)
Precise pressure or temperature regulation loops
Energy-optimized retrofits where analog control is needed
Mixed heating/cooling distribution systems
Large multi-zone systems requiring central control
Precise Modulation — not just on/off, but continuous control for smoother regulation.
Energy Efficiency — consumes moderate power, and avoids overshooting by fine control.
Quiet Operation — minimal noise during actuation, suitable for sensitive interiors.
Compact Build — fits tight valve assemblies without obstructing space.
Robust Construction — durable materials, reliable in daily cycles.
Feedback Output — often includes position feedback (0–10 V) for BMS monitoring.
Universal Mounting — standard M30 × 1.5 thread works with common valve bodies.
Improved Comfort — smooth transitions reduce temperature swings or “hunting.”
