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

  美国斯毕尔公司创新的专利阀座结构与传统的衬里阀座结构阀门区别开来,有利于消除阀座蠕变,降低操作扭矩,加强密封效果。这种高性能阀门特别适用于流量控制或节流,而且可提供各种各样的备选件以丰富和扩展应用范围。完全隔离(干式阀杆),实心316不锈钢阀杆,带备选PTFE涂敷阀杆以增强保护性。可提供标准或真法兰类型的PVC和CPVC材质阀门,通径范围DN40至DN300。可提供标准类型聚丙烯材质阀门,通径从DN40至DN600,此外还可根据用户订购生产DN750至DN1500阀门。高级气动执行器是气-到-气(双作用;备选弹簧复位),配置一对活塞,齿条和齿轮,以及可调节止动装置,并且永久性润滑。强制手动操作装置是标准配置。外壳是硬阳极化铝,并配置环氧树脂涂敷铝盒盖。
  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 stems with optional PTFE coated stems available for extra assurance. PVC and CPVC valves are available in Standard or True Lug style for sizes 11/2" through 12". Polypropylene valves are available in Standard valve style for sizes 11/2" - 24", plus sizes 30" through 60" produced to order. Premium pneumatic actuator is an Air-to-Air (Double Acting; optional Spring Return) featuring twin piston rack and pinion operation with adjustable stops, and permanent lubrication. Manual override is standard. Housing is hard anodized aluminum with epoxy coated aluminum end caps.
