In constant flow applications, the bi-directional ports of a 3-way control valve allow water to bypass the coil or load through mixing or diverting. An actuator is used to force an upward and downward movement of the valve's plug which works to open and close off the different ports to redirect pressure and flow. Mixing applications have two inlets and one
3-Way Mixing Valves vs. 3-way Diverting Valves
In diverting valves the plug closes against the seat. Diverting valves should be used with low differential pressures and electric actuator rather than
These valves are ideal for heating and cooling hot oil, water, and steam applications.
It is very important to orient the valves properly when using 3-way valves in mixing or diverting. 3-way valves are most commonly used as a bypass valve, which can be used on a primary or secondary loop.
