The Mark 2000 is an externally piloted, angle-seat valve with self-adjusting packing gland, intermediate relief, and wiper. The angle-seat construction of the body makes extremely high flow rates possible, particularly in comparison to conventional globe valves.
The compact size and light-weight design makes this valve ideal for OEM machinery and other applications where space is limited.
The Mark 33 is a motor-operated valve featuring the Jordan sliding gate seat and heavy-duty industrial motors for proportional (resistance), on-off, 4-20 mA electronic control. Models include the Mark 33 in sizes 1/4″ through 2″ (DN8 through DN50), the high flow Mark 331/332 with Cv's up to 70 (60,34 Kv), and the Mark 39 with three-way body.
The Mark 37 is a motor-operated control valve that combines a state-of-the-art electronic linear actuator with the exceptional performance of Jordan's sliding gate valve seat design. It’s superior accuracy makes the Mark 37 an ideal final control element in distributed process control systems.
The Mark 39 is a motor-operated, three-way control valve that combines the performance of the Jordan sliding gate seat with the time-proven quality of the Honeywell industrial motor. Available for either diverting (Mark 39) or mixing (Mark 39MX) services, the Mark 39 utilizes two sets of seats to handle higher than usual pressure drops while maintaining ANSI Class IV shutoff.
The Mark 40 and Mark 46 are designed with the unique sliding gate seats for lever control of tanks. Both valves utilize the same design with the exception of the actuator. The Mark 40 is supplied with a float actuator while the Mark 46 is supplied with a lever and a series of drilled holes for attachment to a customer-supplied actuator.
The Mark 44 adjustable cam valve is used to control the flow of fuel oil to a burner. It is ideally suited for process applications with frequent changes in fuel/air mixture because the valve can easily meet new requirements by simply readjusting the cam screws.
The valve is designed for applications where tight shutoff is not required; when required, it must be provided by other means.
The Mark 70 Series is a line of pneumatically-operated, diaphragm control valves that combine multiple spring actuators with the precision of sliding gate seat for closer control and greater accuracy. Jordan's unique sliding gate control valve trim teams up with pressure, temperature, pH, level, or flow controllers for fast response, long-term reliability, and high levels of accuracy on steam, gas, liquid, and chemical services.
The Mark 74 provides long-term, leak-free performance when fugitive emissions are a primary concern. The Mark 74 offers exceptional bellows life with a valve stroke that is just a fraction of that of other rising stem valves. This means Jordan Valve can use a smaller formed bellows that has minimal movement during operation.
The Mark 74 controls fugitive emissions while reducing the risks associated with toxic, corrosive, explosive, and high temperature fluids.
The Mark 75 Series is the next generation of control valves by Jordan Valve with all the benefits of the sliding gate seat design, coupled with the lightweight, compact wafer style body, the Mark 75 provides unparalleled performance and value.
The Mark 75HW is a manually operated, sliding gate control valve. The wafer style body provides great value for the end user while offering all of the benefits of the sliding gate seat. The hand wheel operator allows the user to manually position the valve for optimum flow and lock in place. The valve is available in 1″, 1-1/2″ and 2″ sizes.
While many pneumatic, modulating control valves can be used for on/off service by supplying air pressure to the actuator in excess of the spring range, they are sometimes an inadequate solution to control a process. True on/off control valves, like the Mark 76, offer many advantages over this approach.
The Mark 78 pneumatic control valve is designed for accurate performance and simplified maintenance. It can be used on a variety of applications including viscous/corrosive liquids, process gases, or utility steam in process or utility service.
The Mark 78 utilizes a cage-retained seat design with an unbalanced plug. The top entry cage design allows maintenance while the valve is in the line. The trim comes with stainless steel standard or can easily accommodate special materials for maximum corrosion resistance.
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.
