Morphology

clapper + valve

The compound is directly compositional: 'clapper' denotes a hinged/swinging flap or striker and 'valve' denotes a flow-control device, so a learner who knows both words can infer a valve that uses a hinged flap to control flow and prevent backflow. Although somewhat technical, the construction is predictable and mirrors common cross‑linguistic devices, making the meaning transparent to a learner familiar with the constituents.

Etymology

Clapper valve comes from its moving flap, the clapper, inside the valve. When liquid pushes one way the flap opens, but when the flow tries to go back the flap swings shut and 'claps' to stop it, so it lets liquid go in 'one direction' and 'prevents backflow'.
