Solenoid 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
