3, Main Application And Suitable Medium

This series of check valves are applied to pipe system, as the safe installation of preventing the medium flow back. They are good at non-returning, safety, reliability, small flow resistance, mainly applied to systems of petroleum, chemical industry, food, medication, light textile, water supply and drainage, and energy etc., and used as one-way valve.
