From petrochemicals to agrochemicals, industrial gases to plastics, pigments, and more, the industry that manufactures, processes, transports, and stores thousands of hazardous materials every day requires one thing above all – absolute confidence in the quality, reliability, accuracy, and safety of the devices entrusted with controlling some of the most complex, pressurized, and volatile processes known.
Foxboro’s complete line of robust, field-proven instrumentation provides measurement solutions for temperature, pressure, flow, process analysis, level, and data acquisition. Additionally, our line of valve positioners offers the highest accuracy in the industry.
Jordan Mark 75 Flangeless
Wafer Style Control Valve
Valves are essential to industries which constitute the backbone of the modern world. The prevalence of valves in engineering, mechanics, and science demands that each individual valve performs to a certain standard.
One category of valves are "control valves". These can be linearly operated, or rotary operated. There are many types of control valves, such as gate, globe, ball, butterfly, and plug. All of these valve types have some sort of ball, plug, gate, or disc that throttles the flow as the valve opens and closes. Some valve designs are better suited to uniformly control flow, such as gate valves or valves with specially machined disks. This post is about the Jordan Mark 75, a valve that uses a unique sliding gate design.
According to Wikipedia, "A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level."
The Mark 75 Series control valve is a industrial process control valve manufactured by Jordan Valve. It's design benefits include the sliding gate seat design, low weight, and compact wafer style body. The Mark 75 offers an incredible pricing advantage in the market place due to its wafer style body.
The stroke length of the Mark 75 is a slightly longer stroke than standard sliding gate valves. This longer stroke enables better turndown. Combined with the capacity of the Mark 75, the increased turndown makes for a great control valve.
