 and materials of construction. ASCO Scientific can also custom design a valve for your specific application.
?  Threaded-flat bottom ports available with #1/4-28                 UNF, #10-32 UNF, or M6 threads      
2/2 3/2 Series 458
ASCO Scientific’s patented Series 458 rocker isolation valves feature a unique rocker diaphragm mechanism
 that shields the internal components of the solenoid from the fluid. The design forms an easy to flush,
產(chǎn)品特性：體積超小*度小于120mm，重量0.8KG
全鋼制金屬齒輪傳動（運轉壽命大大超出塑料齒輪），蝸輪輸出，傳動結構簡單可靠。
微型球閥應用于各種對于安裝尺寸和體積有較大限制的工藝場合。
