The UEL Flap Non Return Valve - Female can be fitted to ensure that a medium flows through a pipe in the right direction, where pressure conditions may otherwise cause reversed flow. A non-return valve allows a medium to flow in only one direction. A flap non return valve can only be used on a horizontal pipe. This valve is combined with mixing loops in heating and cooling systems.
