simbi isina tsvina pneumatic 3 nzira yekusanganisa / kutsausa inodzora vharafu

1. compact chimiro, uremu huremu, chiitiko chakanyanya, kuderera kudonha kudonha, kutsva kwepamusoro kunobvumidzwa kudzvanywa, hombe yevharuvhu kugona, kuyerera kwakaringana maitiro uye kugadzirisa kuri nyore, nezvimwewo,
2.Pneumatic 3 nzira yekusanganisa inogadzirisa vharafu inogona kushandiswa kune akasiyana mamiriro ekushanda, kunyanya kune tembiricha yekudzora system yemafuta indasitiri yekutsinhana uye otomatiki kutonga kwemamwe maindasitiri.
3.Spool chimiro nedivi rinotungamira, kugadzikana kwakanaka, hapana kuzununguka, kuderera kwemheremhere, Pneumatic 3 nzira yekubatanidza inodzora valve inogona kutakura mutsauko mukuru, nyore kubatanidza.
4.Nepo ine saizi yakaderera yezita uye kudzvanywa musiyano, 3 nzira yekusanganisa inodzora valve inogona kushandiswa mukutsausa chiitiko.Nekudaro, nepo saizi yezita yakakwira kupfuura DN100 uye yakanyanya kudzvanywa musiyano, Pneumatic 3 nzira yekusanganisa inodzora vharafu uye Pneumatic 3 nzira inotsausa inodzora vharafu haigone kuchinjana.
