York S1-025-46369-000 Expansion Valve 322838-752 Aluminum is the superior choice

Aluminum is the superior choice for high-conductivity water and for systems where traditional magnesium rods react with bacteria to produce odors

Used with Jackshaft Driven Dampers

Applying higher primary voltage will result in immediate component failure and potential damage to the 24V control circuit

this board ensures the combustion cycle remains efficient while preventing short-cycling and unnecessary wear on the heat exchanger

ensuring quiet operation and reduced electromagnetic interference across your motor leads
