美国斯毕尔公司蝶阀高级电动执行机构组件包
Spears® Butterfly Valve Premium Electric Actuation Package

  美国斯毕尔公司创新的专利阀座结构从传统衬里阀座类型阀门分离出来,有利于消除阀座蠕变,降低操作扭矩,提高密封效果。这种高性能阀门特别适用于流量控制或节流,具有各种各样的备选件可供选择,应用功能更加丰富广泛。完全隔离(干式阀杆),实心316不锈钢阀杆,可提供作为备选项的PTFE涂敷阀杆,保护效果更加优异。可提供PVC和CPVC材质的标准或真法兰阀门,通径范围从DN40至DN300。可提供聚丙烯材质的标准阀门,通径范围从DN40至DN600,此外还可根据订单需求生产通径DN750至DN1500阀门。高级电动执行器采用获得美国UL认证的双向电机,内置热过载保护装置。传动装置是永久性润滑,标准配置包括强制手动操作装置。外壳采用耐腐蚀聚酯粉末涂敷铝,抗风雨美国全国电气制造商协会NEMA 4标准,DN15美国标准锥管螺纹NPT管线出口。包括2个单刀双掷限位开关,预置电路为标准115伏交流电连接。
  Spears® innovative patented seat design departs from traditional liner-seat type valves to eliminate seat creep, reduce operating torque and provide positive seal off. Ideally suited for flow control or throttling, this high performance valve offers a full variety of options for greater application versatility. Fully isolated (Dry Stem), solid type 316 stainless steel with optional PTFE coated stems available for extra protection assurance. PVC and CPVC valves are available in Standard or True Lug style for size 11/2" through 12". Polypropylene valves are available in Standard valve style for size 11/2" through 24", plus sizes 30" through 60" produced to order. Premium electric actuator utilizes a reversing type motor with UL approved, built in thermal overload protection. Gear train is permanently lubricated with manual override standard. Enclosure is corrosion resistant polyester powder coated aluminum, weatherproof NEMA 4 rating, 1/2" NPT conduit outlet. Includes 2-SPDT limit switches pre-wired for standard 115 VAC connection.
