Solenoid Valve for Air VRSolenoid Valve for Air VR

VR solenoid air valves are for on/off or high/low control of air flow for combustion systems. Their continuous duty capability makes them especially well suited to withstand the continuous cycling of frequency firing combustion control systems.

Features

  • For continuous duty intermittent high/low or on/off control of combustion airflow
  • Individual high flow adjustment
  • Designed for continuous on-off cycling
  • Life expectancy of 2 million cycles
  • DC system prevents overheating of solenoid coil
  • Damper for speed control
  • Closed position indication and low flow bypass available
  • Low maintenance CE certified models available
  • UL listed
  • CSA approved
