Managing temperature is one of the most important considerations in optimizing vehicle efficiency and performance. The use of a custom, precision-controlled proportional valve or a valve module system can assist in achieving these objectives. A predictable linear control band alongside a coolant system enables maximum control of the vehicle’s temperature. Quick optimization of temperatures helps reduce CO2 emissions as well as response times, resulting in increased efficiency.
To manage temperature in a vehicle application fluid is typically used to dissipate heat. Coolant, which has long been been utilized for mechanical systems, is now also used to manage the temperature of electrical systems. For these applications, coolant can be redirected using a custom proportional valve assembly to help regulate the temperature for batteries, starters, electrical systems and transmissions. Some applications that require thermal control have two inlet fluid temperatures.
There are many different configurations and designs for proportional valves. A typical valve design incorporates ferrous alloy components, copper wire (coil) and a variable orifice designed to meet the necessary requirements of an application.
