Flow Control Valve
FCV-M Series (2-Way)

Direct-drive control valves operating from -40　to 180°C with water, Galden®, Fluorinert™ and　other advanced heat transfer fluids.

Feature

• Direct control of flow or temperature from your PID controller with 4–20 mA, 1–5 VDC or 1–10 VDC
  
• Select flow ranges from 10.4 to 133 LPM / 2.8 to 35 GPM
  
• Fast: 6 seconds from 0 to 100% open
  
• Compact design minimizes space requirements
  
• 3400 steps provide fine, fast valve control
  
• O-ring material selectable to match liquid and temperature range requirements
  
• Connects directly to Tofpine manifold components
  
• Rc connection ports
  
  

  Example Application

  
  Direct control of output from a heat exchanger.
  FCV-M Series Flow Control Valves are controlled by an external PID controller using an accompanying driver unit. Valve position is controlled and continuously monitored by the PID controller with a 4–20 mA or DC signal.
