Abstract

Valves, and particularly check valves, are detailed. The valves may isolate a spring or other biasing member from flowing fluid so as to reduce the possibility of damage to the spring caused, for example, by chemicals contained in the fluid. In some versions of the valves, the spring may be positioned within a cavity of a cover sealed from the fluid.
