The Mark 79 is an air-operated control valve that can accept a 3-15 psi air signal from any of the temperature or process controllers sold by Jordan Valve. It can also be controlled by turbidity, flow, or level controllers and can be set up for direct control or with optional side or top mounted positioners.
The Mark 79 is used for diverting service; ideal for bypassing fluids around coolers or filters. It can also be used as a combining or mixing valve with two inlets and one outlet.
