 Globe/Cage Style Regulators > Mark 58 Series



Mark 58 Series 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 dual inlets or as inlet and outlet for through-flow. It can be installed in a "T" fashion such that the fluid normally flows in one side and out the other side, wit the flow being relieved through 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.

THe Mark 58 is available in sizes up to 2" (DN50) in a wide variety of body materials. Diaphragms can be either stainless steel or yeastier. Low flow versions with Acv values as low as 0.26 (2,24 Kv) are available in certain sizes.
