VRA VLA VTA

Air Solenoid valves

NC solenoid valve for air control fast/slow opening fast/slow closing

The VRA – VLA – VTA types are normally closed solenoid valves for regulation of cold combustion air.

When the coil is unenergized, the spring pushes on the disk to keep the adjusted minimum air passage. The valve opens when the coil is powered, moving the disc to the maximum open position. The valve moves to the minimum position when the power is off.

This type of device is suitable for high/low stage control of combustion air in industrial gas burners.   (qualified for continuous service- 100% ED).
