進口蒸汽調節閥
進口蒸汽調節閥產品概述
進口蒸汽調節閥以單相交流220V電源為動力,接受4~20mA直流信號,自動地控制閥門的開度,從而達到對壓力、溫度、流量、液位等工藝參數的連續調節。是生產過程自動調節系統中的一個重要環節,廣泛應用于電力、冶金、石油、化工、輕工、食品等工業部。
進口蒸汽調節閥產品特點
1、 進口蒸汽調節閥閥芯導向面積大,抗振性好。結構緊湊,輸出力大,可用于控制各種不同壓力和溫度的蒸汽
2、進口蒸汽調節閥配有高精度的定位器及各種膜片、膜盒及感溫器材,能精確控制蒸汽的壓力、流量及溫度等參數。
3、進口蒸汽調節閥的閥體流體通道呈S流線型,壓降損失小,流量大,可調范圍廣,流量特性曲線精度高
4、進口蒸汽調節閥個部件經過細的研磨,消除痕跡,減小或消除密封間隙,提高密封面的光潔度,具有高密封性能。
