止回閥、提升止回閥 - LC 系列 | #4A-LC6L-SS
提升式止回閥設計緊湊，利用重力輔助提升閥密封 -100F 至 900F

Parker 止回閥 - Parker Check Valves
Parker Check Valve, Lift Check - LC Series

Parker 的 LC 系列提升式止回閥設計用于從 -100?F 到 900?F（-148?C 到 482?C）的各種極端溫度。為了達到這種性能，止回閥必須安裝在正確的方向，因為閥帽螺母有明確的標記。與通用提升式止回閥相比，LC 系列的設計可防止反向流動至正向流動的 99.9% 以內。這是液體服務應用的理想選擇。重力輔助提升閥使用背壓實現密封。許多這種類型的工業閥門在連接到管道系統時需要額外的配件（適配器）。LC 系列不需要適配器，并提供與閥體集成的單套圈和雙套圈壓縮端連接。

Parker 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 。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. 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
