ABSTRACT:
Apparatus by which a check valve assembly of a reciprocating pump can be removed. A valve stem of the valve assembly is received within a valve guide which is mounted in a valve guide bracket. The bracket is pivotally attached to a yoke. The yoke is removably fastened to an adaptor. The adaptor is seated in an access port arranged perpendicular respective to the passageway within which the valve seat is mounted. The compressive force of the valve spring maintains the bracket and yoke in assembled configuration respective to the adaptor. The bracket and yoke can be pivoted apart, against the spring force, and removed through the adaptor and then the adaptor can be removed from the access port, thereby gaining access to the remainder of the valve assembly.
