Ụkpụrụ na-arụ ọrụ nke valvụ ụzọ abụọ eletrik bụ na onye na-anya ụgbọ ala na-ebugharị site na moto synchronous reversible na magnetik clutch. Site na iji mmetụta magnetik nke moto site na rotor na clutch moto, enwere ike ịmepụta torsion kwụsiri ike mgbe moto nọ n'ọnọdụ nkwụsị. Ya mere, mgbe moto na-onwem na ugbu a site, ọ nwere ike kwụsị n'ebe ọ bụla stably. Mgbe valvụ meghere ma ọ bụ mechie valvụ ahụ, a na-ekewa njigide magnet ma kwụsịkwa mmezi ahụ.
