RETZ瑞茨/我們一直致力于流體控制和測控領域的持續創新，始于2005……進口氣動針型閥采用兩截閥桿設計，上閥桿螺紋的潤滑脂與系統介質隔離，旋轉的下閥桿上下運動代替旋轉升降，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，確保工作狀態下不會發生泄漏，在相應的溫度下密封件不會發生密封不嚴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

進口氣動針型閥特點 Characteristic
