止回阀、提升止回阀 - LC 系列 | #4A-LC6L-SS
提升式止回阀设计紧凑，利用重力辅助提升阀密封 -100F 至 900F

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

Parker 的 LC 系列提升式止回阀设计用于从 -100?F 到 900?F（-148?C 到 482?C）的各种极端温度。为了达到这种性能，止回阀必须安装在正确的方向，因为阀帽螺母有明确的标记。与通用提升式止回阀相比，LC 系列的设计可防止反向流动至正向流动的 99.9% 以内。这是液体服务应用的理想选择。重力辅助提升阀使用背压实现密封。许多这种类型的工业阀门在连接到管道系统时需要额外的配件（适配器）。LC 系列不需要适配器，并提供与阀体集成的单套圈和双套圈压缩端连接。

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
