Technical specifications and dimensions for Swagelok Series 50 gravity check valves, including pressure ratings, materials, and connection options.
This document describes the Swagelok Series 50 gravity check valves, which limit backflow to pressures up to 413 bar (6000 psig) and temperatures up to 482°C (900°F). The valves operate by using forward flow to lift the disc and reverse flow to seat it against the orifice, requiring horizontal installation with the bonnet nut facing up. They feature a robust stainless steel construction with no springs or elastomers. This manual is written in Spanish.
