Stainless Steel Check Valve with Viton Rubber Poppet

The No. 3395 check valve is made of a one-piece cast stainless steel body, with all internal components also of stainless steel. Designed to operate in any position, a sensitive spring has been added to close the poppet automatically. The rubber poppet is fully-formed around a solid steel insert to provide greater strength in commercial applications. Each valve is tested twice for casting integrity and backflow prevention and is built to last. This model is machined, assembled and tested in the USA with imported castings.
