Bettis Switching Relay
Pneumatic/hydraulic poppet style switching devices that can be manual or pilot operated. Used with high or low pressure control applications.
The Bettis™ Switching Relay, developed by Emerson, is a high-performance pneumatic control device designed to enhance the speed, accuracy, and reliability of valve actuator systems. It functions as a pilot-operated relay that amplifies pneumatic signals and improves air flow to actuators—ensuring rapid valve operation and precise positioning in both on/off and modulating control applications. Built with robust, corrosion-resistant materials, the Bettis Switching Relay is engineered for dependable operation in harsh process environments such as oil and gas, refining, chemical processing, and power generation. The device is designed to handle high-pressure pneumatic control systems, providing fast response times and stable control performance across a wide range of valve automation setups. The compact and modular design allows for easy installation, calibration, and maintenance. It integrates seamlessly with Bettis pneumatic actuators, Fisher positioners, and other Emerson valve automation components, making it ideal for use in complex control networks where precision and reliability are critical.
