GP-2000系列先导薄膜式蒸汽减压阀

曾经，先导式减压阀在其主阀操作部主要是运用活塞， 但随着年代的请求，蒸汽体系的z量进步，也请求减压阀具有更高的操控功能。GP-2000蒸汽减压阀在其主阀操作部替代活塞， 运用膜片，先导薄膜式进步Cv值，对侧压力改变和二次负荷的变动也具有更高的操控功能。

阿姆斯壮减压阀GP-2000特点

· 大减压比高这20: 1 ， 曩昔的两段减压现在用一段即可完成。

· 因为膜片大，又选用外部检查结构，可以操控安稳的二次侧压力。

· 因为Cv值大，流量及操控能力的腾跃进步， 比一般的公称通径小 1~2个号码的商品也可运用。

· 因为阀门为单球形，其密封性进步，渗漏量很少。

. 可办理0.02MPa以下的低压。

GP-2000 Externally Piloted Pressure-Reducing Valves

For steam serviceThe 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).
