世伟洛克® 波纹管密封阀
世伟洛克波纹管密封阀旨在降低泄漏的可能性，其中许多阀门采用无填料设计或焊接密封。在对大气密封非常关键的应用中，此类阀门可提供可靠的无泄漏性能，从而确保操作员的安全并使工艺按预期运行。
查看波纹管阀世伟洛克波纹管密封阀有多种样式和配置可供选择，使用户能找到适用于常规和高纯应用的选项。可选项包括阀体与波纹管之间采用垫片密封或焊接密封、用于关断或调节功能的阀杆头、各种端接、广泛的流量系数范围以及面板安装或底部安装方式。
- 世伟洛克专业的波纹管密封阀配备千分尺手柄，阀杆位置可实现小至 0.001 in. (0.025 mm) 的增量调节，从而实现精确且可重复的流量设定。
- 用于切换功能的紧凑型世伟洛克波纹管密封阀，可通过手动和弹簧复位或双作用气动执行机构将流体从一条管路切换至另一条管路。
- 高压气动驱动的世伟洛克波纹管密封阀能够可处理较高的工作压力和温度，以满足工艺要求
- 部分世伟洛克波纹管密封阀配备二级密封系统，即使主密封失效，也能防止介质泄漏到大气中，从而提高了阀门的可靠性、通用性和安全性。
