Air-Spring Fail-Safe Systems
Safe. Effective. Reliable. Air-Spring Fail-Safe Systems for Mission-Critical Close/Open Valve Applications.
Air-Spring Fail-Safe Systems
Cowan Dynamics air-spring systems provide a reliable solution for large or high-pressure valve applications in which conventional spring-return cylinders are not a mechanically or economically viable option. Designed to trigger a fail-open, fail-close or fail-last condition in the event of loss of power, air supply, or both; fail-safe systems prevent unwanted system conditions from occurring during emergency situations.
Each fail-safe system is engineered to meet your site-specific process control requirements and operating challenges
Worry-Free:
Automated, fully integrated control elements ensure fail-safe protection with little or no maintenance
Reliable:
Fully enclosed control panels withstand the harshest operating or environmental conditions
Secure:
Panels can be padlocked to prevent unauthorized access
Cost-Effective:
World-renowned for their durability, Cowan systems are built to provide years of service

Basic Fail-Safe Systems
Basic air-spring systems include an air tank and pneumatic controls sized and configured to meet specific application needs.
- Air tanks are ASME stamped and available with 20 to 5,000 gallon capacity
- Components are selected based on site-specific requirements: available air pressure, temperature and pressure range, cycle time, number of actuators, number of strokes, etc.
- For harsh environments, the control instruments can be housed in a protective enclosure
Boosted Fail-Safe Systems
Consisting of a basic system to which a Cowan A2A pneumatic booster is added, these systems are designed for applications in which the available air pressure is too low and where space for additional air tanks is limited.
- Cowan’s A2A pneumatic boosters intensify the pressure of the available air supply without the need for additional mechanical or electrical input
- Available in 2:1, 3:1, or 4:1 ratios
- Do More With Less: Smaller footprint of the entire fail-safe system allows users to reduce the actuator size, by increasing the operating pressure
