CVO - Gas Burner Control Valve Orifice for 1/8" or 1/4" NPT Burner Inlet
Select a CVO250 for a Pipe Burner. For a Cast Iron Burner the correct CVO can be selected from the drop down menu of the burner.
What is a Control Valve Orifice?
The CVO250 needle control valve with integral orifice will allow one to fine control the level of the burner flames right at the venturi as opposed to controlling the flame height at the more remote location like at the propane tank regulator or the natural gas source.
A control valve orifice fitting will work on practically any burner if the orifice is drilled to the proper size and you know the size of the gas burner inlet thread (1/8" or 1/4" NPT). The default orifice size is #61 and it can be drilled larger for low pressure propane or natural gas.
Specify your fuel preference of natural gas, low pressure propane, or high pressure propane in the Comments section of the shopping cart.
GasHosesandRegulators will drill it (no extra charge) to the proper orifice size for your particular fuel.
