Check (Non-Return) Valves stop fluid flow in one direction while permitting free flow in the opposite direction.
The force exerted by fluid entering the valve direction unseats a spring loaded poppet permitting fluid to pass. The fluid pressure required to unseat the poppet is known as the force in the opposite direction push the poppet against the seat thus preventing fluid passage.
