The Chemline WE Series Water Check Valve is a non-return valve ideal for limited-space installations. These valves are economical and do not require spacers. They are available in two versions: with or without disc springs. The spring adds force for faster, silent closing. The valves feature compact and lightweight designs that are easy to install in either horizontal or vertical operations. The disc opens fully when installed on ANSI Schedule 80 PVC pipe. The valves are certified to NSF/ANSI Standard 61 for contact with drinking water.
