Equipped with an economizer valve with separate control knob. 

A suitable pilot flame is adjusted with this knob while the trigger is released. 

When the trigger is depressed, the burner returns to the working flame previously adjusted with the standard valve control knob. 

The trigger is easily locked in position and can be operated with one hand. 

The economizer valve saves both time and gas, especially when working a long operation ...with frequent breaks using large burners with heavy gas consumption.
