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. Haina hanya nekumanikidza kumashure uye saka inoshandiswa uko yakajairwa overcenters isingashande nemazvo pakudzora mutoro, ichibvumira kudzvanywa kwakaiswa neiyo system kuti ishandiswe kushanda akati wandei actuators munhevedzano. Flange connections inobvumira valve kuti iiswe zvakananga pane actuator.

Mavharuvhu eBOST e munhevedzano mavharuvhu akapetwa kaviri: anoita basa rekutsigira nekudzora kudzika kwemutoro nenzira mbiri. Iwo mavharuvhu anopikisa maviri anoshandiswa mumaapplication ane bidirectional mitoro izvo zvakakosha kuvimbisa kugadzikana munzvimbo yekushanda uye kudzora mafambiro awo  mavharuvhu ari flangable mavharuvhu, kureva anogona kuiswa zvakananga pa actuator (kazhinji hydraulic cylinder). Kuburikidza neflanging mitsara yekumashure kubva kune cylinder yakabatanidzwa kune inodzorwa mutsara, inodyiswa muchikamu chekuendesa nekuyerera kwemahara kuburikidza maviri cheki mavharuvhu. Counterbalance mavharuvhu mavharuvhu anotyaira anoshanda. Kusimbisa mutsara kune rumwe rutivi kune mutoro, mutsara wekufambisa unoshandiswa uye unotarisira kuvhurwa kwechidimbu chemutsara wekudzika kuti ubvumire kufamba kwekufamba kunyange muhupo hwekutakura mitoro uye kudzivisa cavitation phenomenon. Kutenda kune chiyero chekudzikisa pakati pemutsetse wemutoro uye hydraulic pilot line (pilot ratio), kumanikidzwa kunodiwa kuvhura mavharuvhu kwakaderera pane kuseta kumanikidza. Iyo  double counterbalance valve inokwanisawo kuita basa rekuchengetedza hydraulic system uye mechanical structure yakabatana kwairi, ichiita sevharuvhu isingaite zvekuvhundutsa kana pressure ikanyanya kuitika nekuda kwekuremerwa kwakanyanya kana kukanganiswa netsaona. Iri basa rinogoneka chete kana mutsara wekudzoka pane muparadzi wakabatanidzwa kune dhiraivha. Iyo inonzi semi-compensated counterbalance valve: kuseta kwevharuvhu hakukanganiswe nechero residual pressure pamitsetse yekudzokera, counter-pressures izvo zvinotowedzera kumanikidza kwemutyairi kunodiwa pakuvhura vharuvhu. Rudzi urwu rwevharuvhu saka rwakakodzera kuisirwa mumasisitimu anosanganisira vanogovera vane yakavharika-pakati masiraidhi, ine mashandisirwo akavharwa mune kwaakarerekera.

Chinhu chakakosha chekutsigira mutoro ndeye hydraulic chisimbiso. Kuti ive nechokwadi chekushanda kwepamusoro-soro maererano nekuisa chisimbiso, BOST inotarisisa pakuzadzikiswa kwezvikamu, kubva pakuvakwa kwazvo musimba repamusoro-soro, simbi yakaomeswa uye yakakuya, kusvika pakuongororwa kwedimensional uye geometric, pamwe nekuedzwa kwezvakaunganidzwa. vharafu. Mavharuvhu e counterbalance inhengo mumavharuvhu emuviri: zvikamu zvese zvakaiswa mukati me hydraulic manifold, mhinduro inobvumira kutonga kuyerera kwakanyanya uku uchichengeta zviyero zvakaderera. Ese manifolds akagadzirwa nesimbi, izvi zvinobvumira iyo BOST counterbalance mavharuvhu kushanda nekumanikidza kusvika ku350 bar (5075 PSI) uye inovimbisa kuramba kwakanyanya kupfeka kuti ibatsire hupenyu hunobatsira hwevharuvhu. Nokuda kwekudzivirira kwakakwana kune chiito chevanokonzera kuora, muviri wevhavha uye zvikamu zvekunze hazvisi pasi pekugadzirisa zinc plating. Muviri wevharuvhu wakaiswa panzvimbo dzese nhanhatu kuitira kurapwa kwakanaka. Pazvikumbiro zvakafumurwa kune zvinokuvadza zvakanyanya (semuenzaniso zvikumbiro zvemugungwa) mushonga we zinc-nickel unowanikwa pakukumbira.  mavharuvhu anowanikwa muhukuru kubva kuBSPP 1/4 "kusvika kuBSPP 1/2" yekushanda masimba anosvika makumi matanhatu lpm (15,9 gpm). Uyezve, akasiyana siyana ekuseta uye akasiyana eyeresheni ekutyaira anowanikwa kuti agadzirise zvirinani kune ese marudzi ekushandisa. Nokuda kwekushanda kwakanyatsonaka zvinokurudzirwa kuenzanisa vheji yekupikisa pamutengo we30% yakakwirira kudarika basa guru rekushanda.
