HEP16-PTM帶位置反饋閥門定位器
常陽供應(yīng)的HEP系列電氣閥門定位器有:HEP-15;HEP-16;HEP-17;HEP-15帶位置反饋;HEP-16帶位置反饋;HEP-17帶位置反饋;HEP-15-PTM;HEP-16-PTM;HEP-17-PTM;HEP系列電氣閥門定位器 :HEP型單作用電-氣閥門定位器)是CV3000系列調(diào)節(jié)閥的主要附件。的作用是把調(diào)節(jié)裝置輸出的電信號(hào)變成驅(qū)動(dòng)調(diào)節(jié)閥動(dòng)作的氣信號(hào),而且有閥門定位功能,即克服閥桿摩控力,抵消被調(diào)價(jià)質(zhì)壓力變化而引起的不平衡力,從而使閥門開度對(duì)應(yīng)于調(diào)節(jié)裝置輸出的控制信號(hào),實(shí)現(xiàn)正確定位。
