Description
The Beckett 21981U is a 1-1/2″ two-stage gas valve engineered for precise, reliable fuel control in commercial and residential burner applications. With a low-fire outlet pressure of 1.6″ W.C. and a high-fire outlet pressure of 3.5″ W.C., this valve delivers the staged firing performance needed to optimize combustion efficiency, reduce fuel consumption, and minimize thermal shock to heat exchanger components.
Two-stage operation allows the burner to ignite at a lower fire rate before ramping up to full capacity, improving system longevity and comfort. The 1-1/2″ valve body accommodates higher-flow burner applications and integrates seamlessly into Beckett burner assemblies and compatible OEM systems.
