Valve yakashandiswa kudzora kufamba uye kuvharika kweiyo actuator mumativi ese nekuona kudzika kunodzorwa kwemutoro usingapukunyuki uchikweshwa nehuremu hwayo, sezvo vharuvhu isingabvumiri chero cavitation yeiyo actuator. Hazvina hanya nekumanikidzwa kwemashure uye naizvozvo inoshandiswa apo zvakajairwa overcenters zvisingashande zvakanaka pakudzora mutoro, zvichibvumira kumanikidzwa kwakaiswa nehurongwa kuti hushandiswe kushanda akawanda actuators munhevedzano.
