Abstract

See full text

A valve assembly is disclosed comprising a valve member with an elastomeric upper stem guide and a lower valve guide comprising lateral support members including an angled surface. During operation, fluid impacting the angled surface imparts a rotational force on the lower valve guide and valve member. Consequently, the valve member strikes a sealing member in different rotational positions during repetitive cycling of the valve assembly.
