Check Valves

Strataflo check valves are manufactured from a one piece cast brass body. Each check valve is designed to operate in any position, as a sensitive spring has been added to close the poppet automatically.  The unique conical poppet assembly provides a seal that cannot leak with very low cracking pressure (less than 1 lb.).  Other cracking pressures available.  They are all designed for working pressure of 200 lbs with NPT threads, not for air compressor service.
