The Johnson Controls VA-7088-21 is a linear thermal valve actuator designed for HVAC zone control. It delivers 100 N force, has a 5 mm stroke, operates on 24 VAC, and completes full travel in about 270 seconds.

• Series: VA-7088 electrothermic actuators.
• Function: Provides ON/OFF or proportional control of zone valves in heating and cooling systems.
• Operation: A thermal element expands when energized, slowly moving the actuator stem to open the valve. When de-energized, the valve closes.
• Applications: Fan coil units, terminal units, and other HVAC systems requiring reliable valve actuation.
• Design: Compact and quiet, suitable for confined spaces like fan coil housings.
