When diagnosing a cracked heat exchanger or assessing soot accumulation

By regulating the voltage signals to the motor

Failure to close typically results from debris or scale trapped in the pilot port or a damaged internal needle seat

reducing hunt and maintaining stable valve positioning under varying differential pressures

it eliminates the need for field modifications or generic "universal" workarounds that compromise system efficiency
