品牌：RETZ/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進口氣動針型閥采用兩截閥桿設(shè)計，上閥桿螺紋的潤滑脂與系統(tǒng)介質(zhì)隔離，旋轉(zhuǎn)的下閥桿上下運動代替旋轉(zhuǎn)升降，減低每個過程對填料的磨擦，減少閥座和閥頭之間的咬合，閥門在全開位置具有背密封功能，確保工作狀態(tài)下不會發(fā)生泄漏，在相應(yīng)的溫度下密封件不會發(fā)生密封不嚴retz The pneumatic needle valve adopts a two section valve stem
design. The lubricating grease on the upper valve stem thread is isolated from
the system medium. The rotating lower valve stem moves up and down instead of
rotating up and down, reducing the friction of the packing during each process
and the bite between the valve seat and the valve head. The valve has a back
sealing function in the fully open position, ensuring that there is no leakage
during operation and that the sealing element does not leak tightly at the
corresponding temperature
