阿姆斯壯先導薄膜式蒸汽減壓閥
阿姆斯壯先導薄膜式蒸汽減壓閥
外導式膜片作用減壓閥
適用于蒸汽系統
這種減壓閥類似于內導式活塞式減壓閥(內部采用了一個導閥和一個主閥)。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,與內導式活塞減壓閥相比,在相同的管道尺寸下容量更大。另外,膜片對壓力變化更為敏感,精確度可達+/-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蕩更少。該減壓閥非常靈活,可以采用不同類型的導閥(例如壓力閥、溫度閥、空氣裝載閥、電磁閥或幾種閥同時配套使用)。
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 * 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).
