该系列3PBV塑料自动球阀适用于工业、化工、草坪和灌溉、游泳池和水疗中心的应用,也适用于饮用水。 该阀门采用高效自动化的3座结构,强化TFE阀座和EPDM密封,使用寿命更长,采用全PVC结构,重量轻,经久耐用。 阀门也符合标准配置,可以现场选择NPT或承插式工艺连接。
3PBV是一个经济的自动阀门封装与电动或气动执行机构。电动驱动的型号是耐风雨的,NEMA 4,由标准115vac电源供电,可用于双位置或比例控制。双位置执行机构使用115 VAC输入来驱动每个阀门端口的开启或关闭,而调节执行机构接受4到20ma输入来实现阀门的无限定位。执行机构的特点包括热过载保护,以承受失速条件,视觉位置指示和润滑的齿轮。
气动双作用致动器使用空气供应驱动每个致动器端口。弹簧复位气动执行机构利用供气将阀杆向一个方向驱动,内部加载弹簧将阀门复位到原来的位置。还有SV3电磁阀,用于在空气供应端口之间电动切换供应压力。执行机构采用阳极氧化铝制成,并涂有环氧树脂,使用寿命长。
