SENSING VALVES – KEY FEATURES
• Senses internal position & state
• Electrical feedback via DPST switch ( Double-Pole Single-Throw)
• Directly operated safety-rated force-guided positive-break status switch (DPST)
• Poppet construction for near zero leakage & dirt tolerance
• A diagnostic coverage (DC) of 90% can be obtained by monitoring the safety switch status
• Explosion proof solenoid pilot available, for more information consult ROSS
