Mune hydraulic systems, zvakakosha kuti unzwisise musiyano pakati pevhavha yepamusoro uye acounterbalance valve. Kunyangwe iwo maviri akafanana mune mamwe mabasa, semuenzaniso, ese ari maviri anogona kushandiswa kudzivirira mutoro kubva pakudonha kwemahara, pane misiyano mumitemo yavo yekushanda uye mamiriro ekushandisa.

Musiyano uripo pakati pe-over-center valve uye yakaenzana vharafu

Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhapitiswa (rinonziwo return check valve) iripilot-assisted relief valve ine free-flow check check function. Iyo inonzi pilot ratio inoreva chiyero pakati penzvimbo yekumanikidza mutyairi nenzvimbo yekufashukira. Ichi chiyero chakakosha kune iyo yekumanikidza siyana iyo iyo valve inogona kuenda kubva yakavharwa kusvika yakazaruka yakazara, kunyanya pasi pezvinosiyana zvinorema. A low pilot ratio inoreva kuti mutyairi mukuru wekumanikidza musiyano unodiwa kuti uzarure vharafu. Sezvo simba remutoro rinowedzera, mutsauko unodiwa mukumanikidzwa kwemutyairi wemareshiyo akasiyana emutyairi unova mudiki.

Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ku vhuya ku vhuya, ku vula ku famba kan’we. Kuenzaniswa nepilot-operated check valves, counterbalance valves haikonzeri kufamba kwejerky apo mutoro unodzorwa unoderera. Counterbalance mavharuvhu anowanzo shandisa cone kana spool pressure control zvinhu, ane cone counterbalance mavharuvhu anoshandiswa kudzivirira silinda kukukurwa uye spool counterbalance mavharuvhu anoshandiswa semabhureki mavharuvhu mune hydraulic mota application.
