North American 1807-01-1/2" NPT
An 1807 Limiting Orifice Valve is used to set air/gas ratio on
a nozzle-mix burner. It has a V-port plug that can be adjusted
sensitively and accurately with an Allen wrench. Turning the
screw counterclockwise increases flow. A cap conceals the
adjustment and discourages tampering with the setting. If
an adjustment is needed, replace top cap on valve body to
reduce air or gas leaks.
