A check valve is a one-way valve that allows fluid or gas to flow in only one direction, preventing backflow in heating systems. In boiler and burner applications, it is essential for maintaining proper circulation and protecting components from reverse flow that could cause damage or inefficiency. This valve is commonly installed in water lines, gas lines, or other piping systems within heating equipment. Replacing a faulty check valve helps ensure reliable operation and extends the life of your system.
