Overview

Engineered Controls 3" M NPT Back Pressure Check Valve – Steel Soft Seat DesignThis Engineered Controls A3198S Back Pressure Check Valve is engineered to control and protect flow inside LP gas and propane storage systems. Built with a steel body and synthetic rubber soft seat, this one-way valve ensures a positive seal while maintaining a large flow area for minimal pressure drop.

Designed to protect container openings and prevent reverse flow, this valve is ideal for in-line gas applications where flow must be restricted to a single direction. It is commonly installed inside standpipes, bulk plant systems, and industrial gas piping operations.
