Mark 89/89MX Series- Three-Way Regulator

The Mark 89 is used for diverting service and is ideal for bypassing fluids around coolers or filters. In this configuration, there is one inlet and two outlets. As one inlet closes the other outlet opens, diverting flow from one channel to the other.
The Mark 89MX is used as a combining or mixing valve with two inlets and one outlet. When used as a mixing valve, optimal performance is achieved with equal pressures on both inlets.
