Compared with the electric stainless steel flanged ball valve and the pneumatic stainless steel flanged ball valve, the electric one has better effect on the liquid medium and large pipeline gas, and is not affected by the climate, while the pneumatic one is characterized in that the switching speed can be adjusted, and the structure is simpler, even if it happens In case of failure, it is more convenient to maintain, but the pneumatic stainless steel flanged ball valve is greatly affected by the air pressure, especially in the northern winter, it may be easily affected by the water in the air, causing the transmission part to freeze and not move.
    電動不銹鋼法蘭球閥和氣動不銹鋼法蘭球閥之間是使用不同的驅(qū)動器，這是執(zhí)行機構(gòu)的本質(zhì)區(qū)別，而控制閥本身是沒有什么不同。用不同的執(zhí)行機構(gòu)，主要工作等化學(xué)條件所需的場合證明，目前使用較多的是氣動法蘭球閥，安全性要求高，而且還便宜的智能定位器可以在總線上，控制也很簡單。電動不銹鋼法蘭球閥執(zhí)行機構(gòu)的權(quán)力的來源，如果電路板或容易引發(fā)電氣故障，它一般用于要求較低的環(huán)境中，并沒有危險。在力距的比較上，由于結(jié)構(gòu)的不同，氣動執(zhí)行器的性能也不同，響應(yīng)的速度也不一樣。因此，氣動不銹鋼法蘭球閥動的作力距比電動不銹鋼法蘭球閥更大的。
