外導(dǎo)式膜片作用減壓閥
適用于蒸汽系統(tǒng)
這種減壓閥類似于內(nèi)導(dǎo)式活塞式減壓閥（內(nèi)部采用了一個(gè)導(dǎo)閥和一個(gè)主閥）。但是雙膜片代替了活塞閥。增大的膜片面積能夠打開更大的主閥，與內(nèi)導(dǎo)式活塞減壓閥相比，在相同的管道尺寸下容量更大。另外，膜片對(duì)壓力變化更為敏感，精確度可達(dá)+/-1%。精確性更高是由于下游傳感線的定位，其所在位置氣體或液體動(dòng)蕩更少。該減壓閥非常靈活，可以采用不同類型的導(dǎo)閥（例如壓力閥、溫度閥、空氣裝載閥、電磁閥或幾種閥同時(shí)配套使用）。

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 100% 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).
