The Otto C. Jensen AT30 SR6 appears to be a pneumatic rotary valve actuator, intended for automated operation of quarter-turn valves in marine and industrial piping systems. The SR designation commonly indicates a spring-return actuator arrangement, providing a defined fail position when the compressed-air supply is removed.
Features
- Pneumatic quarter-turn valve operation
- Spring-return actuator configuration
- Provides fail-safe return action when air supply is lost
- Suitable for automatic valve-control systems
- Compact rotary actuator construction
- Can be integrated with solenoid-valve control
- Suitable for position indication/limit switches when appropriately equipped
- Designed for marine and industrial piping applications
- Suitable for frequent automated valve operation
- Useful in centralized machinery-control systems
