1. A device comprising:
a main body including a base portion having an inlet passage and an outlet passage and a body portion extending from the base portion, the body portion in fluid communication with the inlet passage and the outlet passage and including a chamber for receiving a filter;
a valve bonnet having a solenoid bowl for attaching a solenoid and a solenoid vent passage;
a pressure regulator for regulating flow of fluid from the outlet passage;
a cap forming an interface between the body portion and the valve bonnet, the cap including a first portion attached to the body portion and a second portion attached to the valve bonnet, an interior in fluid communication with the body portion, and a cap vent passage extending through a wall of the cap; and
a diaphragm sandwiched between the valve bonnet and the cap defining a pressure chamber between the valve bonnet and the diaphragm,
wherein the solenoid vent passage of the valve bonnet and the cap vent passage of the cap fluidly communicate so that, in an operational state of the device, fluid from the pressure chamber is selectively vented into the body portion to enable moving of the diaphragm away from a valve seat.
