  • Page 3 Introduction ROSS CONTROLS offers a variety of safety valves for use in various safety functions such as safe exhaust, safe return, and safe load holding/stop. This document focuses specifically on ROSS CONTROLS’ 5/2 RSe Series valves that are used for dual pressure safe cylinder return functions and utilize magnetic proximity sensors (PNP) to provide feedback to a safety control system for external monitoring.
  • Page 4 Pilot Supply Conversion The RSe Series valve comes from the factory configured for internal pilot supply which sources pilot supply air pressure internally from port 1 in the valve sub-base. However, when used for dual pressure applications the valve MUST be converted in the field to operate with external pilot supply through the EPS port in the valve sub-base.
