該系列3PBV塑料自動(dòng)球閥適用于工業(yè)、化工、草坪和灌溉、游泳池和水療中心的應(yīng)用，也適用于飲用水。 該閥門采用高效自動(dòng)化的3座結(jié)構(gòu)，強(qiáng)化TFE閥座和EPDM密封，使用壽命更長(zhǎng)，采用全PVC結(jié)構(gòu)，重量輕，經(jīng)久耐用。 閥門也符合標(biāo)準(zhǔn)配置，可以現(xiàn)場(chǎng)選擇NPT或承插式工藝連接。
3PBV是一個(gè)經(jīng)濟(jì)的自動(dòng)閥門封裝與電動(dòng)或氣動(dòng)執(zhí)行機(jī)構(gòu)。電動(dòng)驅(qū)動(dòng)的型號(hào)是耐風(fēng)雨的，NEMA 4，由標(biāo)準(zhǔn)115vac電源供電，可用于雙位置或比例控制。雙位置執(zhí)行機(jī)構(gòu)使用115 VAC輸入來(lái)驅(qū)動(dòng)每個(gè)閥門端口的開(kāi)啟或關(guān)閉，而調(diào)節(jié)執(zhí)行機(jī)構(gòu)接受4到20ma輸入來(lái)實(shí)現(xiàn)閥門的無(wú)限定位。執(zhí)行機(jī)構(gòu)的特點(diǎn)包括熱過(guò)載保護(hù)，以承受失速條件，視覺(jué)位置指示和潤(rùn)滑的齒輪。
氣動(dòng)雙作用致動(dòng)器使用空氣供應(yīng)驅(qū)動(dòng)每個(gè)致動(dòng)器端口。彈簧復(fù)位氣動(dòng)執(zhí)行機(jī)構(gòu)利用供氣將閥桿向一個(gè)方向驅(qū)動(dòng)，內(nèi)部加載彈簧將閥門復(fù)位到原來(lái)的位置。還有SV3電磁閥，用于在空氣供應(yīng)端口之間電動(dòng)切換供應(yīng)壓力。執(zhí)行機(jī)構(gòu)采用陽(yáng)極氧化鋁制成，并涂有環(huán)氧樹脂，使用壽命長(zhǎng)。
