描述
钽闸阀
WDL Tantalum Gate Valve provides full-bore on-off isolation with low pressure loss when open for process systems that need acid resistance in selected highly corrosive chemical processes. Tantalum-wetted construction is considered for severe acid service when corrosion allowance is not an acceptable solution.
设计选项
| 项目 | 可用规格 |
|---|---|
| 材料 | Tantalum-wetted or project-specified construction |
| 功能 | 全通径开闭式隔离阀，开启时压降小 |
| 联系 | 法兰连接或对焊 |
| 操作 | 手轮、减速器、气动或电动执行器 |
| 设计依据 | API 600、API 603、API 6D 或 ASME B16.34 |
典型应用
- Hydrochloric acid equipment
- Sulfuric acid process lines
- Acid recovery systems
- 主进程隔离
- 全口径管道服务
选编说明
Hydrofluoric acid, fluoride salts and strong alkaline media require separate compatibility review and are not default tantalum applications.
通常选择闸阀用于隔离而非连续节流；请确认楔板、阀座和阀杆的设计。
常见问题解答
Why select Tantalum for this gate valve?
Tantalum-wetted construction is considered for severe acid service when corrosion allowance is not an acceptable solution. Final suitability depends on the complete process conditions and the selected valve trim.
