2 way central heating valve
A 2-way central heating valve is a crucial component in modern heating systems, designed to regulate the flow of hot water between the boiler and heating circuits. It operates with two ports-one for incoming flow and one for outgoing flow-allowing precise control of water distribution in the system.
