PR1-1系列美国GO减压阀 PR1系列美国GO多功能减压调节器PR1-1F11Q5J111
减压阀是把阀前较大的压力减低成为较小压力的一种设备。背压阀也可叫溢流阀，是为了将阀前压力保持在设定值，将多余压力排出的一种设备。因此减压阀是控制阀后压力的，而背压阀是控制阀前压力的
PR-1系列是一种多功能减压调节器，设计用于满足仪表样品系统和半导体加工气体等其他应用的广泛需求。PR-1的许多特性使其成为广泛应用的理想选择，可以在气体或液体应用中控制低到中等流量的压力。316L阀体材料用于促进焊接连接。不锈钢盖和调节螺钉可防止大气腐蚀并保持外观。增强的内部车身表面光洁度优于25 Ra加上电抛光，使清洗更容易，并可能减少流中的颗粒污染。五种不同的阀座材料、三种不同的原始尺寸和七种压力控制范围（带不锈钢隔膜），用户可通过多种能力进行压力控制，入口压力高达6000 psig，标准工作温度高达500°F（260°C）
订货须知：介质，温度，出入口压力，流量系数（CV值），接口尺寸，是否带压力表等。
