Gas Valve Orifices - Whirlpool 4322452 Service Manual

An orifice is an opening used to control the direction and amount of gas that is discharged to a
burner. Orifices are available in different sizes and shapes and can be removed and replaced
without replacing the valve.
PLUG-TYPE ORIFICES
The cooktop burner orifice uses a plug-type orifice, as shown in Figure 3-5. The orifice is generally
constructed of brass, and consists of a threaded seat, a chamber, and a metered hole. The
threaded seat allows the orifice to be securely fastened to the burner valve. The chamber is used
as a passageway to allow gas to flow through the orifice opening. The orifice is used to control, or
limit, the amount of gas going to the burner. This type of orifice is not adjustable.
