高级蝶阀，配置最高耐腐蚀性阀瓣与阀杆，适用于化工与食品加工业。优异的密封设计结构使得阀座与阀瓣/阀杆之间实现完全密封，完全避免出现污染事故。除此之外，每一个Sure Seal（稳密）阀门都经过严格测试，达到全部额定压力的百分之一百一十的标准要求。
The superior butterfly valve with the most corrosion resistant standard disc and stem for the chemical and food processing industry. Superior encapsulated design results in total encapsulation of the seat and disc/stem, providing the ultimate in contamination free service. In addition, every Sure Seal valve is tested to 110 percent of full pressure rating!

特点与优点
Features and Benefits
- 阀杆采用标准255双相不锈钢，具有更高的耐腐蚀性，强度接近316不锈钢的两倍，无需再担心阀轴扭曲和水锤损害
Stem is standard 255, a duplex stainless which is more corrosion resistant and almost twice as strong as standard 316 stainless steel, eliminating shaft twisting and water hammer damage
- 顶部安装台按照标准钻孔模板进行机加工，适配手动手柄组件，以及执行机构，还可提供ISO模式的可更换性
Top plate is machined to standardized drilling pattern allowing manual handle kits, and actuation, interchangeability also available in ISO patterns
- 阀杆套管由足够强度耐腐蚀聚酯组成 - 能够吸收操作装置侧向冲力
Stem brushing composed of full strength, corrosion resistant ertalyte - aborbs operator side thrust
- 第三重阀杆密封确保外部及内部的绝对密封，适用于真空或压力应用领域
A third stem seal ensures absolute seal externally or internally for vacuum or pressure service
- 拥有两个专利的O形密封圈提供第二重加强密封，使得O形密封圈成为阀体的组成部分，在阀杆安装进入阀座和阀瓣区域之前，就包裹在阀杆周围
Two patented O-seals give a sure secondary seal as the O-seal becomes part of the body and encircles the stem before entering the seat and disc area
- 阀门中枢部位和阀座的密封装置防止流体损害阀杆或阀体
Hub and seat seals prevent product from attacking stem or body
- 凸耳型阀体预先钻孔攻丝加工出凸耳，符合美国国家标准协会ANSI 125和150法兰标准
Lug-style body has drilled and tapped lugs which meet ANSI 125 and 150 flange standards
- 法兰密封件对规格内的所有法兰提供绝对可靠的密封
Flange seal provides an absolute seal to all flanges within specifications
