Description
The Sensus-Gas Division 143-62-023-44 Orifice For 143 is a precision flow restriction tool applied in HVAC systems and gas-fired heating equipment to control the flow of fuel to the burner. It is sized with a 3/8″ orifice to fit into the proper jet holder or manifold to offer a gas passage area to be used in combustion to allow a consistent delivery of fuel at the required pressure. This orifice, mounted in the gas train in front of the burner assembly, is vital in ensuring the gas valves and burners are compatible and that the air-fuel mixture and combustion operation are stable.
