B735型,也叫压力顺序阀,是一种全平衡、经济的调节器。与635型相似,但其流速更高。主要用于压缩机上调节过滤器和分离上的后压,因此提高其效率高达1000%。不锈钢的阀芯的设计使它具有自我清洁能力。不依赖出口压力,它能供给稳定的后压(设定压力)。当出口压力(例如正在充气的容器)到达设定压力时,调节器完全打开,允许自由流动。一般情况下后压设定为1500~3750PSI,当然,也可设定到低至600PSI的压力。可订购比标准轻的弹簧以提高低压操作。
OPERATION
In operation the back pressure regulator will maintain it's set pressure upstream and allow just enough gas flow to hold this pressure. The set pressure can be adjusted by loosening the 3/8" jam nut and turning the adjusting screw. Set pressure is pressure at the inlet port when gas is flowing through the regulator.
