Why would I need a gas burner Control Valve Orifice?
The CVO series needle control valve orifice allows one to adjust the height of the burner flames directly at the venturi rather than further back at the propane tank regulator or the natural gas source. This Control Valve Orifice fitting will work on practically any gas burner if the orifice is drilled to the proper size and you know the size of the gas inlet thread (1/8" or 1/4"). Indicate your fuel preference of either natural gas, low pressure propane, or high pressure propane in the Comments section in the Shopping Cart. The default orifice size is #61 for High Pressure propane. However, we will drill it to the proper orifice size for your particular fuel. No extra charge.
