00:00:06,250 --> 00:00:17,292
The univalve assembly changes the cooling water flow paths through the cooling system to regulate the water temperature during different operating conditions.

00:00:17,292 --> 00:00:24,708
The univalve assembly consists of a rotary flow control valve assembly shafted to a three-position pneumatic actuator.

00:00:24,708 --> 00:00:34,500
The three univalve control magnet valves (WFV1, WFV2, and WFV3) are used to switch the actuator.

00:00:34,500 --> 00:00:42,958
To troubleshoot the univalve, an indicator on the actuator provides a visual indication of what mode of operation the assembly is in.
