Valv Tcheke
Yo itilize pou anpeche refoule, tiyo sa yo tipikman aktive tèt yo, sa ki pèmèt tiyo a ouvri otomatikman lè medya a pase nan tiyo a nan direksyon li te prevwa a epi fèmen si koule a ranvèse. Sa gen ladan tiyo chèk ki pa retounen an, tiyo chèk an fè fonn, tiyo chèk tip Wafe, tiyo chèk an bout fil, tiyo chèk doub plak, ak tiyo chèk bride, elatriye.
