Mark 58 Series – Globe Style Back Pressure Regulator
The Mark 58 back pressure regulator features three ports: a bypass outlet on the bottom and two side ports which are directly connected to serve as inlet and outlet for flow-through. It can be installed in a “T” fashion allowing fluid to flow in one side and out the other with the flow relieved via the bottom bypass when the pressure exceeds the setting. It can also be installed with one side port as an inlet and the other side port plugged. In this arrangement, when the inlet pressure exceeds the set point, fluid is relieved through the bottom port.
