电、气动法兰球阀概述Electric, pneumatic flange ball valve Overview
该系列法兰球阀为软密封浮动球阀,采用了防静电、防爆出的阀杆设计,并有防火设计可选。中轴有蝶型弹簧自动压紧填料,使用寿命设计为10万次,维护期长;加之阀体上有ISO5211安装平台设计,电气动球阀体积小,不受安装方向限制,被客户广泛认可。(阀连接:国标,美标,德标,日标(可选)。产品多用于化工,水处理,工业气体,食品制药与机械制造等行业。
Flanged ball valves of the series for soft sealing floating ball valve, the use of anti-static, explosion-proof stem design and fire safety design options. Axis there is a butterfly spring automatically compress the packing design life of 100 000 long maintenance period; ISO5211 installation platform design coupled with the valve body, the electro-pneumatic valve, small size, free from the restrictions on mounting direction, customers widely recognized . (Valve connection: GB, American standard, German standard, Japanese standard (optional). Products used for chemical, water treatment, industrial gases, food, pharmaceutical and machinery manufacturing industries.
