功能介紹 Function introduction
進(jìn)口電動(dòng)高壓球閥是由鍛鋼高壓閥體及電子式角行程電動(dòng)執(zhí)行器組成。電動(dòng)執(zhí)行器采用一體式結(jié)構(gòu)，輸入220V電源即可直接進(jìn)行開關(guān)量調(diào)節(jié)，亦可內(nèi)置伺服模塊，輸入控制信號(4～20mADC或1～5VDC)及單相電源即可控制運(yùn)轉(zhuǎn) retz The electric high-pressure ball valve is composed of forged steel high-pressure valve body and electronic angular stroke electric actuator. The electric actuator adopts an integrated structure. It can directly adjust the switching value by inputting 220V power supply. It can also be equipped with a servo module. It can control the operation by inputting control signal (4~20mADC or 1~5VDC) and single-phase power supply
