Description
The Honeywell V4943N1038 is a single-stage pressure regulating valve engineered for reliable natural gas flow control in commercial and industrial heating applications. Featuring a 1-1/2″ pipe connection and 120VAC operation, this valve delivers precise pressure regulation with a factory-set outlet pressure of 3.5″ water column and field-adjustable high-fire regulator setpoints ranging from 3″ to 4.5″ water column — giving technicians the flexibility to fine-tune performance to system requirements.
With a generous capacity range of 780 to 2,300 CFH, the V4943N1038 is well-suited for medium-to-large burner systems. Its controlled actuation timing — a maximum 6-second valve opening time and a maximum 2-second valve closing time — ensures smooth, safe gas delivery and shutdown, protecting equipment and meeting combustion safety standards.
