Maintaining proper fuel-to-air ratios is essential for HVAC combustion efficiency

this auxiliary component enables secondary circuit control

Standard HVAC code and manufacturer specifications require these valves to be installed in a vertical orientation with the discharge piping directed downward to prevent scaling and trapped debris

Durable Construction: Built with high-grade alloys to resist corrosion and thermal stress within the combustion chamber

Designed as a direct-fit OEM replacement flame rollout switch

Johnson Controls V46BD-2 Regulating Valve 30067439-890 Maintaining proper fuel-to-air ratios isThe Johnson Controls V46BD 2 is a heavy duty, direct acting water regulating valve engineered specifically for maritime and corrosive environments. Designed to modulate water flow to lead side condensers, this 1 inch NPT water regulating valve responds directly to refrigerant pressure increases to maintain stable head pressure. Built with a maritime type cast naval bronze body and Monel interior parts, the V46BD 2 is resistant to the aggressive
