偏心旋塞阀遵循美国水行业协会（AWWA） C517 标准，可用于处理清洁及污浊的气体和液体、泥状及浆状物料。 流通口是100%的标准管面积，包括直通阀体带冲洗口的设计可使流量最大化和压损最小化。矩形端口设计提供了在几何数理上的公差给阀座使阀门有优良而持久的关闭。包括耐腐蚀轴承、焊接镍制阀座、除砂器、可调整的填料、多种弹性旋塞面可供选择等特点。
Eccentric Plug Valves comply with AWWA C517 and are used to handle clean and dirty liquids, sludge, slurries and gases. They can be used for either isolation/shutoff or throttling/control services.Port is 100% of standard pipe area, including straight through body desingn with flushing port to maxinmize flow capacity and reduce head loss. Rectangular port design provides wide tolerance seating geometry for lasting superior shutoff. Standard features include corrosion resistant bearings, welded nickel seat, grit excluders, adujustable packing and a choice of resilient plug facings.
