American Standard flange regulating valve is the the the various regulator valve, flange connection dimensions conform to ANSI 150Lb 300Lb 600Lb standard, American standard flange connection can be used to require the American Standard 150Lb or 300Lb 600Lb ANSI flanged connectionsOfficial Road on a variety of pressure reducing valve, to do vacuum regulator valve. American Standard regulating valve can be used to control the flow of air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media, such as various types of fluid.
美標(biāo)調(diào)節(jié)閥有以下特點(diǎn):
1、采用美標(biāo)法蘭,適用于需要裝配美標(biāo)法蘭的管道,方便安裝更換。
2、除了閥蓋處襯套導(dǎo)向外,閥芯側(cè)面與閥座內(nèi)表面也有導(dǎo)向作用,導(dǎo)向面積大,工作可靠。
3、伺服放大器采用深度動(dòng)態(tài)負(fù)反饋,可提高調(diào)節(jié)精度。
4、電動(dòng)操作器有多種形式,可適用于4~20mA.DC或0~10mA.DC。
5、電子型電動(dòng)調(diào)節(jié)閥可直接由電流信號(hào)控制閥門開度,無需伺服放大器。
6、節(jié)省自動(dòng)化投資,與單座、雙座或套筒調(diào)節(jié)閥相比,組成同樣的系統(tǒng)可省掉一個(gè)閥,簡化系統(tǒng),節(jié)省投資。
7、若驅(qū)動(dòng)器已經(jīng)裝到閥體上,那么在安裝調(diào)試過程中絕對(duì)不能對(duì)驅(qū)動(dòng)器施力,否則會(huì)損壞驅(qū)動(dòng)器
