GP-2000CS 是一种大排量、高性能的外部先导式减压阀。通常用于间断排放，应用领域包括换热器、蒸汽盘管、旋转式干燥机、工艺设备和加热系统等。
调节蒸汽压力
GP-2000CS 拥有 20:1 的调节范围和高 Cv，性能可靠、精度高（5% 到 *** 流量时，***到压力设***的+/-1%），能长期无故障运行。钨铬钴合金不锈钢工作部件可在线更换。GP-2000CS 是应用于终端的单座式减压阀，提供 NPT (1/2"–2") (15–50 mm) 和 2"–4" (50–100 mm)法兰连接两种规格。
GP-2000 外部先导减压阀 - 故障排除
下游压力持续上升时
测试主阀和导阀：
隔离阀门
拧松调节螺栓
拆除导阀和主阀反馈管
打开蒸汽
如顶部端口有蒸汽泄漏，可能导阀有脏物
更换导阀密封圈 K-2110
如中间端口有蒸汽泄漏，可能主阀有脏物
清洗主阀和阀座
GP-2000 Externally Piloted Pressure-Reducing Valves
For steam service
The GP-2000 is a high-performance, externally piloted reducing valve for large-capacity requirements. Typical use is on intermittent service, including applications such as heat exchangers, steam coils, rotating dryers, process equipment and heating systems. With a 20:1 rangeability and high Cv, the GP-2000 is reliable and accurate (+/-1% of pressure set point from 5% to *** of flow) over a long, trouble-free service life. Hardened stainless steel working parts are renewable in-line. The GP-2000 is single-seated for dead-end service, and it is available with both NPT (1/2"–2") (15–50 mm) and flanged connections in 2"–6" sizes (50–150 mm).
