Description
Monaco Dynamic – Wax Hydraulic Fan Control Thermovalve – 553/1/09857/200
This hydraulic wax thermovalve is engineered to regulate cooling fan operation in motorhome applications, including Monaco coaches. As engine temperature increases, the valve gradually closes off bypassing hydraulic fluid from the switching valve. This initiates movement of the spool valve, redirecting pressurized fluid to the fan motor.
The hotter the engine gets, the further the spool shifts, increasing hydraulic flow and ramping up fan speed to deliver responsive, temperature-based cooling performance.
Features:
-
Controls hydraulic fluid flow to engine cooling fan
-
Responds to temperature changes with progressive activation
-
Compatible with hydraulic fan systems on select Monaco motorhomes
-
OEM replacement for 553/1/09857/200
-
Also referred to as a wax valve or Dynamatic thermo valve
Applications:
Typically used in Monaco, Holiday Rambler, and other coaches equipped with Dynamatic hydraulic cooling fan systems.
