GP-2000 系列先導(dǎo)薄膜式蒸汽減壓閥
以前,先導(dǎo)式減壓閥在其主閥操作部主要是使用活塞, 但隨著時代的要求,蒸汽系統(tǒng)的質(zhì)量不斷提高,也要求減壓閥具有更高的控制性能。GP-2000蒸汽減壓閥在其主閥操作部取代活塞, 使用膜片,先導(dǎo)薄膜式提高Cv值,對一次側(cè)壓力變化和二次負(fù)荷的變動也具有更高的控制性能。
阿姆斯壯GP-2000減壓閥特點
· 可以減壓比高這20: 1 , 過去的兩段減壓現(xiàn)在用一段即可實現(xiàn)。
· 由于膜片大,又采用外部檢測構(gòu)造,可以控制穩(wěn)定的二次側(cè)壓力。
· 由于Cv值大,流量及控制能力的飛躍提高, 比通常的公稱通徑小 1~2個號碼的產(chǎn)品也可使用。
· 由于閥門為單球形,其密封性提高,滲漏量極少。
. 可管理0.02MPa以下的低壓。
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).
