벨로우즈 밸브는 다양한 유량계수와 스템팁 재질 옵션으로 일반산업 및 고순도 서비스에서 대기중으로 누설을 방지하기 위하여 패킹이 없는 구조와 용접된 밀폐를 사용하였습니다.
View Bellows ValvesSwagelok bellows-sealed valves are available in a variety of styles and configurations, allowing users to find options that work well in their general and high-purity applications. Options include gasketed or welded body-to-bellows seals, stem tips for shutoff or regulating service, a variety of end connections, a wide range of flow coefficients, and panel or bottom mounting.
- Specialized Swagelok bellows-sealed valves with micrometer handles allow for precise, repeatable flow setting by allowing stem position changes in as little as 0.001 in. (0.025 mm) increments
- Compact Swagelok bellows-sealed valves for switching service allow for flow to be changed from one line to another using manual and spring-return or double-acting pneumatic actuators
- High-pressure, pneumatically actuated Swagelok bellows-sealed valves can handle elevated working pressures and temperatures to match process requirements
- Select Swagelok bellows-sealed valves feature a secondary containment system that prevents leaks to atmosphere even if the primary seal fails, enhancing reliability, versatility, and safety
