Abstract:
A valve assembly including a body having an inlet port, an outlet port, and a valve seat having a passageway. An electrical solenoid assembly moves a valve member upon being energized to control fluid flow between the inlet and the outlet ports. The valve assembly also includes a fluid-tight bellows positioned to apply a force to the valve member, and a pressure balancing passageway connects the inlet port to the bellows. The valve assembly further includes a housing received over the solenoid assembly and having a flange received against the valve body. A seal is positioned between the flange of the housing and the valve body, and a collar is secured in a continuous manner to the valve body over the housing flange, thereby securing the housing to the valve body and applying a sealing force to the seal in a substantially even manner.
