(144) The MK60 Sliding Gate Pressure Regulator is used to regulate the downstream pressure to a predetermined setpoint. 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. The actuator required for the valve will ...
(16) The Mark 601 and 602 meet higher capacity requirements than standard regulators. The High Flow Mark 601 has Cv’s as high as 50 (43 Kv) and the Super High Flow Mark 602 has Cv’s up to 70 (60.2 Kv). Each valve comes with Jordan’s Sliding Gate Seats, which help to reduce the droop commonly associated with high flow regulators.
(72) The Mark 62 internally piloted pressure regulator is a specialty valve designed for critical application regulation in locations where space is limited. Small and lightweight in design, the MK62 valve provides the accuracy of a piloted valve with the size, weight and appearance of a single, self-operated valve. As the MK62 is self operating, it is suitable for use in locations where accurate regulation is needed, but air or electric supply may not be readily available. With the compact design, limited space applications is no problem, making it ideal for use on skids, or as an upgraded replacement for smaller regulators. The integral pilot design also means lighter weight, placing less stress on supported piping.
(320) The Jordan Mark 63 is designed to maintain a constant differential between the pressure on the discharge side of the regulator and the signal pressure loaded on the diaphragm. The Mark 64 provides the same flow capacity as the Mark 63 but with less offset in controlled pressure due to a larger diaphragm.
The Mark 63CDF features a flow-through spring housing that is designed to permit “in-oil-line” installation. This is especially desirable where air or steam is used for fuel oil atomization. The fuel oil flow through the spring housing reduces the possibility of the oil asphalting on top of the diaphragm which would cause a loss of differential pressure control and operating sensitivity. For added protection in this service, the Mark ...
(32) Jordan vacuum regulators control very accurately and shutoff tightly to maintain the proper vacuum setting. They are used to maintain vacuums at predetermined settings and to regulate vacuums on evaporators, cookers, grinding fixtures, milking machines, altitude chambers and other vacuum systems.
(45) The Mark 66 is a highly accurate and economical air loaded pressure regulator that provides regulation from a local station or from a remote station. The operation of the MK66 requires no control spring or pilot. Instead, a static air signal is applied to the top of the diaphragm to determine the setpoint. The MK66 has a rangeability of approximately 40:1; the same as our pilot-type sliding gate regulator, the MK67. However, unlike other piloted regulators, the MK66 has no minimum differential pressure requirement, and, because of its lack of a pilot valve, the MK66 is not as susceptible to problems caused by dirty service.
The MK66 setpoint is adjusted by controlling the air pressure supplied to the top of the diaphragm. This ...
(160) The MK67 Series is for critical pressure reducing applications and provides greater accuracy and lower offset than can be achieved with a self-operated regulator. The MK67 is part of the sliding gate regulator offering. In the case of the MK67 regulator, the much shorter stroke of the sliding gate, combined with the action of the pilot valve, create a faster and more accurate (less droop) response. This allows a shorter travel for the seats to reach optimal positioning, with less diaphragm movement.
(144) The Mark 68G is a globe-style pressure reducing regulating valve that offers high capacity, accurate regulation, and easy servicing, making it the ideal choice for your industrial-grade pressure reducing applications. The bottom-entry design ensures the Mark 68G is easy to clean or repair. The diaphragm can be easily accessed from the top allowing some repairs to be conducted without removing the valve from the line.
(30) The Mark 68HP is designed primarily for high pressure steam service as commonly found in power plants, refineries, pulp & paper mills, and other high pressure process applications. Since high pressure superheated steam is routinely used for power generation (turbines), a pressure regulator capable of withstanding these pressures is needed for the distribution of lower pressure steam for individual process requirements. Common uses for the Mark 68HP include:
Pressure reduction of turbine extraction steam to desuperheaters.
Steam injection to turbine bearing seals to eliminate pressure differential across this area.
Primary pressure reduction from the main steam header to lower pressure points of use.
(15) The MK608 Gas Pressure Regulator is the ideal valve for low pressure gas regulation. The self-contained low pressure gas regulator is for use on tank blanketing, gas meter inlet pressure regulating, gas burners and other low pressure air and gas applications. The MK608 is normally open. Increases in the outlet pressure are sensed through the aspirator causing the large elastomer diaphragm to rise, which moves the plug toward the seat. As outlet pressure decreases, the diaphragm moves down and moves the plug away from the seat to increase flow. The lever, which connects the stem to the diaphragm, amplifies diaphragm forces for tighter shutoff (only available on sizes 3/4” through 1-1/4”). The large diaphragm and lever actuation allows the ...
(4) The Mark 618 is a spring-loaded pressure regulating valve for use in maintaining precise pressure set points in low pressure gas and liquid services. The Mark 618 maintains the downstream pressure at settings from 1” water column to 7 psi (3 mbar to 0.5 bar). The Mark 618 is completely self-operated and requires no external power source or air supply for operation. Regulator may be fitted with the diaphragm casing in either a horizontal or vertical position. The horizontal position is preferable.
(32) The Mark 686 is a cage trim pressure reducing valve that features air-loading, high capacities, accurate regulation, and easy servicing, making it an exceptional choice for your pressure regulating applications. The bottom-entry cage trim allows simple cleaning or repair all working trim parts can be removed from the body as one assembly. The diaphragm is easily accessible from the top, allowing maintenance without removing the valve from the line.
(45) The MK6800HP is a line of self-operated pressure regulating valves for use on high pressure industrial gas and liquid services to 4,000 psi (275.8 bar). The MK6800HP features exceptional accuracy with high flow capacities and simple in-line maintainability.
For durability and dependable service, the 1/2” - 1” valves are constructed of total barstock, with all stainless steel components. The stainless steel plugs are available with hard seats, or with a variety of soft seats that include Stellite, Zymaxx and Teflon. Balanced trim can be provided with all seat types.
