Product--HEAT-MEDIUM THREE-WAY CONTROL VALVE


WY-D22TD	WY-D22TD	–Features: 　Heat-medium three-way control valves are generally used either to mix flowing medium or to divert one medium into two outlet flows and are often used when fluid temperature is to be adjusted though heat exchangers. 　 Mixing type valves can also be used for diverting service when both the valve size and pressure differential are small. However, the mixing type is more suitable when the valve size is larger than 3" and the pressure differential is also considerable.
