Consider one valve limit switch with the versatility and ease of use to be used throughout the plant: Stonel Axiom. The Axiom not only has all components incorporated integrally, it is a space efficient design utilizing the most flexible components for most applications: 20-125 VAC or DC monitoring feedback and solenoid control; 5-way, 2-position solenoid control with selection for either direct acting or spring return actuators in two Cv flow capacities for a wide range of actuators; bus communication modules and low power solenoid valves, re-breather solenoid functions, and manual override …. all in a very rugged package. Check out the video and see for yourself, then contact Mead O’Brien to get started with the Axiom in your applications.
