Screwed SS316 and SS304 Check Valve Cast Steel Swing Check Valve

1. Introduction

Swing check valve, as the name implies, also uses a swinging disc to allow or block flow. The difference between the two is in the body design. Swing check valves are not designed for extremely tight spaces like the wafer check. They have molded bodies around the area where the disc opens up. This is the most important difference between the two types of valve. 

2. Application

Swing check valves on the other hand, have a molded body that creates room for the disc to swing open fully, thus allowing full flow. As you can imagine, this is immensely important if your application requires full flow. For this reason, we recommend wafer check valves for applications where flow is not an issue, and swing check valves when a full port valve is required.
