Umgaqo wokusebenza wevalve yehydraulic usekwe kubuchwephesha bolwelo kunye nethiyori yolawulo, kwaye undoqo wayo ulele kwintshukumo ehambelanayo phakathi kondoqo wevalve kunye nomzimba wevalvu. Xa iimpawu zolawulo lwangaphandle (ezifana nemiqondiso yombane, imiqondiso yomatshini okanye imiqondiso ye-hydraulic) isebenza kwi-spool, i-spool iyakoyisa amandla entwasahlobo, ukungqubuzana kunye nolunye uxhathiso, okukhokelela ekufudukeni, ngaloo ndlela kutshintshe ubungakanani be-valve port okanye ukuvula nokuvalwa. urhulumente. Olu tshintsho luchaphazela ngokuthe ngqo indlela yokuhamba, uxinzelelo kunye nokuhamba kweoli ye-hydraulic, kwaye emva koko iqonda ukulawulwa kwenkqubo ye-hydraulic. Ngokomzekelo, kwi-valve yesikhokelo, ukujikeleza okanye ukuguqulelwa kwe-spool kunokutshintsha indlela yokuhamba yeoli, ukwenzela ukuba i-actuator ikwazi ukufezekisa ukunyakaza kwangaphambili okanye ukubuyisela umva; Kwi-valve yoxinzelelo, ukuvulwa okanye ukuvala i-spool kusetyenziselwa ukulawula uxinzelelo lwenkqubo ukuqinisekisa ukuba lusebenza ngaphakathi kwendawo ekhuselekileyo.
