FESTO電磁閥,費斯托正確用途

FESTO電磁閥響應時間可以短幾個毫秒，即使是導式電磁閥也可以控制在幾十毫秒內。由于自成回路，比之其它自控閥反應更靈敏。設計得當的電磁閥線圈功率消耗很低，屬節能產品；還可做到只需觸發動作，自動保持閥位，平時點也不耗電。電磁閥外形尺寸小，既節省空間，又輕巧美觀。（4）調節精度受限，適用介質受限。電磁閥通常只有開關兩種狀態，閥芯只能處于兩個極限位置，不能連續調節，（力圖突破的新構思不少，但還都處于試驗試用階段）所以調節精度還受到定限制。電磁閥對介質潔凈度有較高要求，含顆粒狀的介質不能適用，如屬雜質須濾去。另外，粘稠狀介質不能適用，而且，特定的產品適用的介質粘度范圍相對較窄。（5）型號多樣，用途廣泛。電磁閥雖有天不足，優點仍十分突出，所以就設  1
