RSe Series Double Valve Safety Category. 4 PL e, External Monitoring

  • Redundant control can achieve Category 4, PL e, when used with proper safety controls
  • Can be utilized for Safe Return Dual Pressure Applications to control pressure in order to extend a cylinder with the supply pressure at port 3 and retract with the supply pressure at port 5
  • Can be utilized for Safe Pressure Select Applications in order to safely control the pressure applied to a machine operation
  • Each single valve in the RSe Series is equipped with a PNP proximity sensor
  • Monitoring both of these sensors on each actuation and de-actuation of the RSe Series valve provides a diagnostic coverage up to 99%
  • Monitoring of these sensors is to be done by an external monitoring system
  • Redundant spool type valve with two operating solenoids that must be operated simultaneously in order to actuate the valve. In addition each valve element has a single, proximity sensor that is wired as a PNP type sensor for position sensing
