Stainless Steel Check Valve with Stainless Steel Poppet

The No. 3400 check valve is made of a one-piece cast stainless steel body, with all internal components also of stainless steel. The proprietary stainless steel poppets are finely machined for a metal-to-metal seal. Designed to operate in any position, a sensitive spring has been added to close the poppet automatically. Each valve is tested twice for casting integrity and backflow prevention. All valves are 100% American-Made and built to last.
