    PBD DIRECT OPERATED PRESSURE RELIEF VALVES

    Kufotokozera Kwachidule:

    Ma valve othandizira a PBD ndi mtundu wa poppet womwe umagwiritsidwa ntchito mwachindunji kuti achepetse kuthamanga kwa hydraulic system. Mapangidwewo akhoza kugawidwa mu poppet (Max.40Mpa) ndi mtundu wa mpira. Pali sikisi mavuto kusintha ranges zilipo 2.5;5;10;20;31.5;40Mpa. Ili ndi mawonekedwe a mawonekedwe ophatikizika, magwiridwe antchito apamwamba, ntchito yodalirika, phokoso lochepa komanso moyo wautali wautumiki. Mndandandawu umagwiritsidwa ntchito kwambiri ku machitidwe ambiri otsika otsika, angagwiritsidwenso ntchito ngati valavu yothandizira ndi valavu yakutali, ndi zina zotero.
