This is typically used to increase cooling water flow to a heat exchanger as the process temperature increases

the valve opening point should be verified

reducing mechanical stress on the primary heating assembly and gas valves

which is essential for maintaining system static pressure and indoor air quality

ASCO S261SH02N3EG5 Valve 321702-401 This is typically used toThe ASCO S261SH02N3EG5 Valve is an engineered solenoid safety gas valve designed for high performance on off control within industrial and commercial combustion systems. This normally closed (NC), pilot operated shutoff valve features a durable die cast aluminum body, making it a reliable choice for managing fuel gas in gas burners and boilers. Optimized for efficiency, the 3 4" NPT port and 3 4" orifice support a high flow capacity (Cv of 8. 0) and a
