The spring in the Mark 60 holds the sliding gate seats in their normally open position to allow the process media to pass through the seats. The downstream pressure is sensed beneath the diaphragm. As the downstream pressure exceeds the setpoint, pressure is exerted on the diaphragm which raises the stem to modulate the disc (the moveable component on the sliding gate seat set) toward the closed position. As the seats close, downstream pressure will be reduced to the required setpoint. A decrease in pressure relaxes the spring and diaphragm to move the seats toward the open position. This brochure includes the following Series: • MK60: a line of self-operating pressure regulators designed with Jordan Valve’s sliding gate seats • MK61: The MK61 features a larger diaphragm than a standard MK60 to provide even greater sensitivity and minimal offset from a required setpoint • MK60QC: The MK60QC features a “Quick Change” dome for simple range spring replacements. Ideal for facilities with multiple pressure reducing applications - stock one valve with several spare springs to cover a wide range of needs • MK60H: The MK60H features a handwheel that replaces the adjusting screw for easy changes to the setpoint • MK60HP: Working pressure fully rated to ANSI Class 600 pressures, the HP options permits setpoints as high as 450 psi • MK60GP: The MK60GP option requires grain processing modification for starch cookers and other viscous services • MK601/602: The MK601 and MK602 meet higher capacity requirements than standard regulators Pressure Regulators Mark 60 Self-Operated Pressure Regulators MARK 60 FEATURES • Sliding Gate Trim — unique seat design for unsurpassed trim life and accuracy. • Jorcote Seat Coating — ceramic composite for liquids, gases and especially steam. Very low friction with outstanding wear resistance. Steam tested to 1,000,000 cycles and still maintained Class IV leakage. • Jorlon Diaphragm — extremely durable, virtually universally applicable up to 450°F, standard 316 SST diaphragm applicable up to 650°F. Tested without failure to over 1,000,000 full stroke cycles. Ideal for steam, gases and liquids. • Straight-through Flow — The flow is straight through the valve seats and body. Direction of the disc travel is perpendicular to the flow, not opposed to the direction of the flow. Thus, the flow does not unbalance the seats. The MK60 can use a wider range of its stroke to give accurate control; less offset. • Quiet Operation — typically 5-10 dB less than conventional globe style regulators. The disc and plate are always in contact, which eliminates chattering. Straight-through flow minimizes turbulence. Multiple orifices in the plate and disc divide the flow stream into smaller flow components. • Minimum Maintenance — The MK60 sliding gate seats require no special tools for disassembly. The seats are pre-lapped at the factory and are self-lapping while in operation ensuring a continual tight shutoff.

MK60 SELF-OPERATING PRESSURE REGULATORS The Jorlon Diaphragm - Revolutionary Diaphragm Sets New Standard Easily retrofitted - Jorlon can be easily retrofitted in the field with no additional parts. For regulators purchased after the fall of 1991, only the diaphragm needs to be changed to retrofit either SST or elastomer diaphragms. Chemical Compatibility — Jorlon is PTFE based, so it is compatible with most media except fluorinated gases and halogenated fluorocarbons. Whether the application is steam, process gases or fluids, Jorlon should be your first choice. High Pressure Limits — The MK60HP...
