Swagelok® Bellows-Sealed Valves
Swagelok bellows-sealed valves are designed to limit the potential for leaks, with many featuring a packless design or welded seals. They provide reliable, leak-tight performance in applications where the seal to atmosphere is critical to keep operators safe and processes functioning as intended.
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
