WP Series Wafer Checks (2″ – 12″) Compact

The Chemline WP Series Wafer Check Valve is a non-return valve ideal for limited space installations. These valves are economical and available for large pipe sizes, 2″ to 12″ and larger. They are available in two versions – with or without disc springs. The spring adds force for faster, more silent closing.

PW Series Wafer Check (3″ – 10″) Standard

The Chemline PW Series Wafer Check Valve offers high end features at reasonable cost. This wafer check does not require a separate spacer or flange gaskets. The large orifice and full flow design means low pressure drop. Spring assisted disc closure is standard as well as an optical indication of disc open/close position. A selection of body materials and elastomers allow for a wide range of applications.
