Description
The No. 395 check valve is made of a one-piece cast brass body. 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. All valves are 100% American-Made and built to last.
Application
Used for resistance in aggressive fuel and chemical applications or where excellent heat stability is required. Rated for temperatures up to 350°F. Not for steam use.
