美国CAT 型号：7021

该压力调节器专为单泵或多泵、抽吸或多喷嘴系统而设计。这是一种流通式设计，很容易连接到排放管线或直接连接到排放头上。即使只有几个喷枪或喷嘴中的一个在执行或电磁阀打开时，该调节器也能保持设定的系统压力，从而绕过未使用的流量。在全旁路期间压力保持在管路中，当所有喷枪和喷嘴恢复操作时立即具有全压。5-10% 的旁路对于性能是必要的。

CAT  Model: 7021

This Pressure Regulator is designed for single or multiple pump, weep or multi-nozzle systems. This is a flow-thru design easily plumbed into the discharge line or directly onto the discharge head. This regulator maintains set system pressure even when only one of several guns or nozzles is performing or a solenoid valve is open, by-passing the unused flow. The pressure is held in the line during full by-pass and instantly has full pressure, when all guns and nozzle resume operation. 5-10% by-pass is necessary for optimum performance.
