PR-1 Series Adjustable Pressure Reducing Regulator
GO PR1系列是一种多功能减压阀调节器旨在满足广泛的需求仪器样品系统和其他应用如半导体加工气体。 许多PR-1的特点使其非常适合各种应用控制压力在低到中等气体或液体介质中的流动。 采用316L机身材质以方便焊接连接。 不锈钢盖和调节螺钉防止大气腐蚀并保持外观。 增强的内部主体表面光洁度优于 25 Ra 加电抛光
允许更轻松的清洁和可能更少的颗粒流中的污染。五种不同阀座材料，三种交替孔口尺寸和七个压力控制范围与不锈钢隔膜为用户提供了广泛的范围入口压力升高时的压力控制能力高达 6000 psig 和标准工作温度至 500° F (260° C)。
