A stop cum non-return valve, also known as a check valve, clack valve, one-way valve, or retention valve, is designed to allow fluid to flow in one direction only, therefore preventing the liquid or gas from flowing back upstream of the valve.
Non-return valves are used in systems where it is desirable to make sure fluids flow mostly in one direction, but may not be critical, for example in pumped systems such as heating circuits. For additional information regarding the product, please contact with dubuy support team.
