Product Overview

The CV-S0-S is our line of stainless-steel swing check valve. A Swing Check Valve is one of the simplest ways to prevent back flow and is generally inexpensive. This check valve has a disc that swings freely on a hinge. The disc is only permitted to swing in one direction allowing fluid to flow through in that direction but will slam shut when gravity or upstream flow becomes stronger than the flow downstream. Both gravity and backflow help to close the swinging disc against the valve’s seat, creating a seal.

Unrestricted Media Flow

Swing check valves are extremely useful for pipes with a steady flow of media. These valves are great for applications with high, consistent flow and horizontal applications. They allow for a much larger opening than a spring check valve because the disc is able to move much further out of the way. If your application requires flow not be restricted this check valve is a great solution.

Quality SS Construction

The CV-S0-S line of swing check valves is both affordable, and with its simple design, can last a long time. Our CV-S0-S series is molded out of Stainless steel with all Stainless-Steel components with Female NPT threading. This valve can withstand temperatures up to 356° F and pressure up to 200 PSI.

While this valve is extremely sturdy and easy to maintain, swing check valves should not be used in certain applications. Because it relies on gravity, it is not able to restrict flow when installed in certain positions. It is designed to be in the horizontal position; however, it can also be in the vertical position if it is meant to be allowing flow up and preventing flow from coming back down as gravity will be pushing the disc down towards the valve seat. Simply put, if the disc is naturally closed in that position, the valve should function properly; if the disc is naturally open in that position, the valve will not function properly. This check valve should not be used in applications where the sudden pressure changes regularly occur. Because this valve is closed by the back pressure any sudden reversal of pressure will cause the valve to slam shut and may damage the disc, ball seat, or both, leading to media passing in the wrong direction.
