Abstract: In a thermal fluid system, a control valve includes a flow valve and a solenoid pilot valve. The flow valve has an inlet and an outlet; a control chamber for receiving a pilot pressure; and a valve member operable by the pilot pressure to selectively open and close a fluid path from the inlet to the outlet. The pilot pressure acts in a closing direction of the flow valve. The pilot valve provides the pilot pressure to the control chamber and is a 3/2 way valve with a first port in fluid communication with the control chamber, a second port to be connected to a pressure source, and a third port. The pilot valve has a first position connecting the first port with the second port and a second position connecting the first port with the third port.

Abstract: A solenoid assembly (100) is provided that includes a frame (104), a coil (106) positioned proximate the frame (104), and a core (114) defined by the coil (106). A plunger (108) is actuatable between at least a first position and a second position, and a guide (109) is at least partially disposed within the core (114). The plunger (108) is disposed at least partially within the guide (109). A housing (102) at least partially houses the frame (104), the coil (106), the guide (109) and the plunger (108), and the guide (109) is prevented from rotating independently of the housing (102).
