这个螺纹式旋转关断阀使流通能力较大的大直径管道能被逐渐关断隔离。这个阀门关断形式有效降低了系统产生的液压冲击波或水击作用，可能对钢管或管接件产生的损伤。派克的Conflow 18/19系列也可以用于消防栓的直列止回阀，大幅降低对下游设备的损坏。它也可以用来隔离阀门进行维护。 This screwdown valve enables large flows in large diameter pipes to be isolated by the gradual shut off of the valve. This eliminates hydraulic shock waves or water hammer being created which would damage the steel pipes and fittings. Used as an inline stop valve for a fire hydrant, Code 18/19 prevents damage to downstream equipment. It can also be used to isolate valves for maintenance.
该阀门在全开位置提供了真正的全流量能力，从而在管道中产生更小阻力。4英寸产品采用了平衡压力特性，使阀门能够在高压工况下以更小力矩开启和关闭。 The fully open position gives a true full flow capability thus creating minimal resistance in the pipeline. The 4" unit incorporates a balanced pressure feature, which enables the valve to be opened and closed at high pressure with the minimum of effort.

派克的Conflow 18/19系列可提供的尺寸有2，2-1/2，3和4英寸的大小和符合工作压力上限为105bar（Conflow 18系列），125bar（Conflow 19系列）。 Code 18/19 is available in 2", 2 1/2", 3" and 4" sizes and operates at a maximum working pressure of 105 bar (Code 18), 125 bar (Code 19).
