Valve and pressure regulator biasing assemblies

摘要

An embodiment of the present invention relates to self-contained biasing assemblies for use with fluid flow devices or assemblies, such as valve and pressure regulator assemblies. A self-contained biasing assembly of a fluid flow assembly can be readily changed without requiring substantial disassembly of the fluid flow assembly. The biasing force applied to components within the fluid flow assembly can be changed by changing the biasing assembly.
