Control Units

CU4 & CU4+ Series

  • Automated control and position monitoring for reliable processing
  • Reduces compressed air and electrical connections 
  • Helps reduced external solenoid valve cabinets
  • Accelerates valve response time 
  • Innovative seat lift detection is fully integrated without need for external sensor wiring to provide additional position monitoring 
  • Reliability and long service life- robust clamp connection, reinforced stainless steel air coupling threads to avoid air leakages, and water tight seals 
  • Ease of operation- contains manual override solenoids and adjustment screw to throttle air flow to actuator to ensure optimal opening and closing 
  • Clarity- clear and bright indication of valve position- 5 dioes in LED panel and convenient location 
  • Standardization- same control top used on other SPXFlow valves lines 
  • NEMA 6 washdown rating
