進口電動防爆調(diào)節(jié)閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進口電動防爆調(diào)節(jié)閥---（Explosion-proof electric control valve），采用防爆型的電動裝置，具有具有高智能、高防護性能、體積小、集成度高、使用壽命長、性能穩(wěn)定等特點，廣泛應用于電力、石油、化工、冶金、環(huán)保、輕工、教學和科研設備等行業(yè)的需要防止介質(zhì)與火花爆炸的工業(yè)過程自動控制系統(tǒng)中。電動防爆調(diào)節(jié)閥屬于頂部導向型控制閥，配由3810系列電子式電動執(zhí)行器，電動執(zhí)行機構內(nèi)有伺服放大器，無需另配伺服放大器，有輸入控制信號（4～20mADC或1～5VDC）及單相電源即可控制運轉，實現(xiàn)對壓力、流 量、溫度、液位等參數(shù)的調(diào)節(jié)。

Introduction of imported electric explosion-proof control valve products:
Explosion proof electric control valve imported from German Locke With the characteristics of high intelligence, high protection performance, small volume, high integration, long service life and stable performance, it is widely used in the industrial process automatic control system to prevent medium and spark explosion in the power, petroleum, chemical, metallurgy, environmental protection, light industry, teaching and scientific research equipment industries. The electric explosion-proof control valve belongs to the top oriented control valve, which is equipped with 3810 series electronic electric actuator. The electric actuator has a servo amplifier without additional servo amplifier. It can control the operation with input control signal (4 ~ 20mADC or 1 ~ 5VDC) and single-phase power supply to realize the adjustment of pressure, flow, temperature, liquid level and other parameters.
