    Parker 單向閥
    Parker Check Valves
    單向閥,提升單向閥 - LC系列 Check Valve, Lift Check - LC Series

    派克 LC-系列提升單向閥結構緊湊,利用重力輔助提動頭密封,廣泛應用于儀器儀表系統中的多種嚴苛溫度 Parker's LC-Series Lift Check Valves are a compact design and utilize a gravity assisted poppet to seal a wide variety of temperature extremes in instrumentation systems

     

     

    派克LC系列提升單向閥設計溫度范圍廣泛,-100?F -900?F (-148?C - 482?C)。為達到此性能,單向閥應如閥帽螺母所示水平安裝.相較于普通的提升單向閥,LC-系列的設計,以防在相反的方向流動到99.9%的正向流動。這就是流體制動的概念。重力輔助的提動頭利用背壓達到密封效果。 Parker's LC-Series Lift Check Valve has been designed for a wide variety of temperature extremes from -100?F to 900?F (-148?C to 482?C). To achieve this performance, the check valve must be mounted in the proper orientation as the bonnet nut is clearly marked. In contrast to a general purpose lift check valve, the LC-Series has been designed to prevent flow in the reverse direction to within 99.9% of forward flow. This is ideal for liquid service applications. The gravity assisted poppet uses back pressure to achieve a seal.

    這類工業閥大多數在與管路連接時需額外加接頭(轉接頭),LC系列無需額外的轉接頭,使用與閥門一體的單/雙卡套連接方式 Many industrial valves of this type require additional fittings (adapters) when connecting to tubing system. The LC Series does not require adapters and offers both single ferrule and two ferrule compression end connection integral to the valve body
