Three Way Solenoid Valve for Water and Gas Hot Water Boiler Heating System Suppliers and Manufacturers

Water (Hot water) Gas Three-Way Solenoid Valve

Essential Function

An electromagnetic driven valve specifically designed to control the flow of water (including hot water) and gas media, which switches the connection status of three interfaces (one inlet and two outlets/two inlets and one outlet) through electrical signals to achieve media diversion, merging, or flow direction switching.

Core structural characteristics

Three interface design: including one inlet (P), two outlets (A/B) or two inlets (P1/P2), and one outlet (A), the channel combination is changed by the displacement of the valve core.

Electromagnetic drive: The coil is energized to generate magnetic force that drives the valve core to move, cutting off or connecting designated channels (opening port A and closing port B with normally closed energization).

Temperature and pressure resistance: The valve body is made of stainless steel/copper alloy, and the sealing components are compatible with PTFE/NBR materials. It can withstand hot water up to 180 ℃ and pressure up to 40 bar.
