Product Description
North American MFG. CO. Limiting Orifice Valve 1-1/4", 1807-2
PN: 1807-2
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 a screwdriver. 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.
