Maintaining a reliable standing pilot ignition system requires components that can withstand constant thermal stress while delivering precise millivolt output

while the manual override button allows for easy commissioning and mechanical system checks

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

and TFI timings that do not drift over the life of the control

Johnson Controls V46BD-2 Regulating Valve 30067439-890 Maintaining a reliable standing pilotThe 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
