The integrated Tefzel characterizing disc offers the precise throttling capabilities of a globe valve with the high close-off pressure (200 psi) typical of a robust ball valve assembly
Its robust construction resists clogging from gas-borne particulates
Using it with non-LF actuators will result in improper fitment and potential mechanical failure
Enhanced Durability: Industrial-grade components withstand the high-cycle demands of commercial HVAC control systems
Always verify furnace part compatibility by checking the inducer mounting pattern and transition dimensions
Allanson 421-664 Transformer 30067439-890 The integrated Tefzel characterizing discThe Allanson 421 664 ignition transformer is a critical replacement component engineered specifically for Webster Engineering burners. This heavy duty oil burner transformer operates on a 120V AC supply voltage and delivers a consistent 10,000V secondary voltage at 23mA, ensuring reliable arc stabilization for efficient combustion. Designed with a mid point ground configuration, this unit minimizes electrical interference and enhances safety during
