Description
This valve is designed to be mounted, with a drop of sealant, in a spare top bush or tapping in the dome of the boiler. A remotely mounted servo with rod can then be used to activate the valve lever through 90 degrees. A 1/8″ coned union and nut are provided for silver soldering to a whistle pipe. Adjustment of the lever is achieved by loosening the spindle lock nut, moving the lever and re-tightening it. Thread lock can be applied if desired. The inlet thread is 1/4″ x 32 tpi.
