krom//schroeder霍科德系列是一種新型的燃氣與空氣比例調節(jié)閥。它主要應用在諸如各種工業(yè)窯爐、燃燒爐等需用燃氣與空氣比例調節(jié)的地方。比例閥的功率域(工作極限)問題。對于直動式電液比例節(jié)流閥，由于作用在閥芯上的液動力與通過閥口的流量及流速(壓力)成正比，當電液比例節(jié)流閥的工況超出其壓降與流量的乘積即功率表示的面積范圍(稱功率域或工作極限)時，作用在閥芯上的液動力可增大到與電磁力相當?shù)某潭?，使閥芯不可控。類似地，對于直動式電液比例方向閥也有功率域問題。當電液比例方向閥的閥口上的壓降增加時，流過閥口的流量增加，與比例電磁鐵的電磁力作用方向相反的液動力也相應增加。當閥口的開度及壓降達到一定值后，隨著閥口壓降的增加，液動力的影響將超過電磁力，從而造成閥口的開度減小，**終使得閥口的流量不但沒有增加反而減少，此即為電液比例方向閥的功率域的概念。在選擇比例節(jié)流閥或比例方向閥時，一定要注意，不能超過電液比例節(jié)流閥或比例方向閥的功率域。

隨著國內工業(yè)的快速發(fā)展，直接促使燃氣減壓閥的普遍運用，尤其是在治金行業(yè)還有就是石油化工等領域的使用，尤其是燃氣比例閥穩(wěn)定的性能還有質量的可靠性在行業(yè)競爭中顯得越來越重要了。與同規(guī)格的伺服閥相比，比例閥的成本大約是其50%。然而，安裝比例閥也是很有講究的。例如燃氣入口壓力偏低。打個比方，比例閥入口燃氣壓力只有3kpa，那么不考慮壓損的情況下，比例閥出口壓力比較大只能為3kpa，而此時如果空氣管壓力在3kpa以上，比例閥出口燃氣壓力也不會升高。正確做法：空燃比例閥入口壓力Pe一定要高于空氣控制壓力PL，否則再高的空氣壓力也不能提高嘴前燃氣壓力。
