防爆電動(dòng)閘閥防爆型防護(hù)等級(jí)為IP68,是少數(shù)*擁有礦用煤安證和防爆證的企業(yè)之一。礦用防爆電動(dòng)閘閥適用于易燃易爆的場(chǎng)合,安全系數(shù)高、操作功能強(qiáng)、性能穩(wěn)定等。防爆型產(chǎn)品有dI和dIIBT4兩種，dI適用于煤礦非采掘工作面；dIIBT4用于工廠，適用于環(huán)境為IIA、IIB級(jí)T1～T4組的爆炸性氣體混合物。

礦用防爆電動(dòng)閘閥的性能符合JB/T8528-1997<普通型閥門電動(dòng)裝置技術(shù)條件>的規(guī)定。防爆型的性能符合GB3836.1-2000<爆炸性環(huán)境用防爆電氣設(shè)備通用要求>及JB/T8529-1997<隔爆型閥門電動(dòng)裝置技術(shù)條件>的規(guī)定。并經(jīng)國(guó)家防爆電氣產(chǎn)品測(cè)試中心檢定，取得了防爆合格證。

礦用防爆電動(dòng)閘閥調(diào)節(jié)模塊可接收和輸出4～20ma標(biāo)準(zhǔn)信號(hào)。電氣元件安裝在一塊可翻轉(zhuǎn)的板上，以便對(duì)力矩控制、行程控制器、開(kāi)度機(jī)構(gòu)進(jìn)行調(diào)整。按鈕盒上有三個(gè)按鈕，中間為現(xiàn)場(chǎng)/遠(yuǎn)控轉(zhuǎn)換按鈕，其左邊現(xiàn)場(chǎng)關(guān)閥按鈕，右邊為現(xiàn)場(chǎng)開(kāi)閥按鈕，蓋上按鈕盒為遠(yuǎn)方控制，打開(kāi)蓋子為現(xiàn)場(chǎng)操作。
