Zosefera za compressionvalavu ya mpirandi gawo la mapaipi omwe amaphatikiza kusefera ndi ntchito zowongolera kuyenda. Valavu iyi imasindikiza chithunzi cha fyuluta munjira yoyenda ya valve yachikhalidwe ya mpira. Sing'anga (madzi, mafuta kapena madzi ena) ikamadutsa, imachotsa dothi, dzimbiri ndi zonyansa kudzera pa sefa. Kenako, pozungulira pachimake cha valavu ya mpira 90 °, payipi imatha kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu. Chifukwa chake, pokwaniritsa kuwongolera koyenda, sing'angayo imasefedwa ndikuyeretsedwa.

Njira yolumikizira "compress" imagwiritsa ntchito zida zapadera kuti zisindikize mawonekedwe pakati pa chitoliro ndi valavu mwamphamvu, kupanga chisindikizo chodalirika ndi kugwirizana kwa makina, kuonetsetsa kuti ntchito yosindikiza ndi kukhazikika kwadongosolo la payipi.

Pazabwino zogwiritsira ntchito, valavu ya mpira wa compression ili ndi maubwino angapo: imatenga mapangidwe ophatikizika, kuphatikiza kusefera ndi kuwongolera ntchito kukhala imodzi, kuchepetsa zopangira mapaipi, ndikusunga malo oyika ndi ndalama; Ikhoza bwino zosefera zonyansa, kuteteza mavavu otsika, zida, zida zosatha, etc. kutsekeka ndi kuvala, ndikuwonjezera moyo wawo wautumiki. Valve ya mpira ndiyosavuta komanso yopulumutsa ntchito kuti igwire ntchito. Kulumikizana kwa clamping ndi kukhazikitsa kumakhala kofulumira, ndipo ntchito yokonza pambuyo pake monga kuyeretsa chophimba chosefera ndi yabwino kwambiri. Ili ndi ntchito yabwino yosindikizira komanso kukana kukakamiza nthawi imodzi, imatha kusungabe kutayikira pansi pa kupanikizika kwambiri, ndipo ndi yoyenera pazikhalidwe zosiyanasiyana zogwirira ntchito zamadzimadzi.

Valavu ya mpira wa compression, yokhala ndi maubwino ake ophatikizika a "sefa + control", magwiridwe antchito ndi kukonza bwino, komanso magwiridwe antchito odalirika, yakhala gawo lofunikira lomwe limagwira ntchito komanso lachuma pamakina a mapaipi, ndipo limakhala ndi udindo wofunikira m'magawo angapo ogwiritsira ntchito boma ndi mafakitale.

Mavavu a Jinbin adakhazikika pakupanga ma valve kwa zaka 20. Ndi luso lamakono ndi chitsimikiziro cha khalidwe, timangopanga ma valve apamwamba kwambiri monga mafakitale a butterfly valves, valve valves, welded mpira valve, blind plate valve, wall mounted penstock valve, zitseko zamtengo, ma valve a mpweya, ma Jet Valves opanda kanthu, ndi zina zotero.
