Abstract
The present disclosure discloses a multi-component valve system for use in pumps such as fracking pumps for use in subterranean resource production. The assembly includes a retaining pin having a retaining cap on its upper end. Located on the retaining pin are an insert retainer, an insert beneath the insert retainer, a valve beneath the insert, and a guide beneath the valve. The guide has a generally truncated pyramid shape, and a central portion on its upper end. The central portion is centered on the retaining pin. The retaining pin has an expanded lower end to secure the valve assembly together.
