ABSTRACT:
A valve comprising an electromagnetic solenoid assembly, a valve assembly, and a fastening device is provided. The fastening device is configured to removably couple the electromagnetic solenoid assembly to the valve assembly. The fastening device is retained by the electromagnetic solenoid assembly when the electromagnetic solenoid assembly is uncoupled from the valve assembly. The valve assembly may include a valve body having a valve seat surface and a valve element having a seating surface to seat against the valve seat surface. The valve seat surface may include a resilient sealing element and a hard stop element, such that the valve element in a closed, seated position provides a substantially zero leakage valve closure.
