FAQs & Support

Pilot-operated pressure regulators are used in applications where self-operated regulators cannot provide the required level of pressure control, flow capacity, or pressure stability (low droop). A pilot regulator senses downstream pressure and feeds a signal to the main valve actuator, allowing near-controller-level accuracy without external instrumentation.

Jordan Valve offers the Mark 67/69 Series pilot-operated pressure reducing regulator for critical high-flow pressure-reducing applications in sizes 1/2″ to 6″, and the Mark 57 Series pilot-operated back pressure regulator with setpoint ranges from 10 to 185 psi, turn-down ratios up to 50:1, and Cv values up to 395 – suitable for steam, air, gas, liquids, and chemicals.

Both series feature Jordan’s sliding gate seat for straight-through flow, reduced turbulence, fast response, and quiet operation.

The best differential pressure regulator depends on the application and whether the system needs to maintain a constant pressure differential on the upstream or downstream side of the regulator.

Differential pressure regulators maintain a set pressure difference between two points in a system rather than controlling pressure to a fixed setpoint. They are used in industrial applications where maintaining a consistent pressure differential is critical to process performance.

Jordan Valve manufactures both differential pressure reducing and differential back pressure regulators for industrial applications.

The Mark 63/64 Series is a differential pressure reducing regulator designed to maintain a constant differential between the downstream pressure and a separate signal pressure. The Mark 64 features a larger diaphragm for greater sensitivity in applications requiring tighter control.

For applications requiring differential back pressure control, the Mark 53/54 Series maintains upstream pressure at a set differential above the signal pressure. The Mark 54’s larger diaphragm provides increased sensitivity for applications where small changes in pressure are important.

Selecting the appropriate differential pressure regulator depends on the process media, pressures, flow rate, temperature, required differential and whether upstream or downstream pressure needs to be controlled. A Jordan Valve authorized representative can review the application and help size and select the appropriate regulator.

The best steam pressure reducing valve for an industrial boiler system depends on the inlet and outlet pressures, steam temperature, minimum and maximum flow requirements, and required control accuracy.

Jordan Valve manufactures pressure reducing regulators for industrial steam applications, with several designs available to meet different pressure and flow requirements. Many feature Jordan’s proprietary sliding-gate technology, which provides a short stroke for fast response and a straight-through flow path designed to reduce turbulence, noise and wear.

For many general industrial steam applications, the Mark 60 Series provides self-operated pressure reduction in a compact sliding-gate design. Higher-pressure applications may require the Mark 60HP Series, while applications with high flow rates or widely varying steam demand may benefit from a pilot-operated regulator such as the Mark 67/69 Series.

Proper sizing is especially important in steam service. An undersized regulator can create excessive steam velocity and noise, while an oversized regulator may operate too close to the seat and provide poor control.

The best regulator should therefore be selected based on the actual steam conditions rather than pipe size alone. Jordan Valve’s JVCV sizing software or an authorized Jordan Valve representative can help size and select the appropriate steam pressure regulator for the application.

Jordan Valve specializes in pressure regulators and control valves featuring our proprietary sliding-gate technology, originally developed in 1947.

Unlike conventional globe-style designs, the Jordan sliding gate uses a stationary plate and moving disc with multiple matched orifices. The disc moves perpendicular to the flow to precisely regulate pressure, temperature or flow. This design provides a short stroke, fast response, low-noise operation and tight shutoff while helping reduce wear on critical components.

Jordan Valve offers sliding-gate technology across a broad range of pressure reducing regulators, back pressure regulators, differential pressure regulators, temperature regulators and pneumatic control valves for steam, gas, liquid and chemical applications.

A pressure-reducing regulator works by force balance, using four main components: a set screw, spring, diaphragm, and plug.

The compressed spring and diaphragm are the two opposing forces, and the plug acts as the balance between them. The set screw compresses the spring to establish the desired setpoint – a compressed spring generates a downward force that opens the plug and allows more flow.

If downstream pressure rises above setpoint, the diaphragm is forced upward against the spring, closing the plug and restricting flow. If pressure drops, the spring pushes down, opening the plug to allow more flow through.

In Jordan Valve’s sliding gate regulators, the diaphragm drives a short-stroke sliding gate seat rather than a long-stroke globe plug.

The stroke length in Jordan regulators is typically one-third that of an equivalent globe valve, which reduces droop, extends diaphragm life, and delivers faster response to pressure changes.

Jordan’s proprietary Jorlon diaphragm enhances accuracy compared to metal diaphragms, as its flexibility more closely resembles elastomer materials while maintaining high pressure ratings.

The best industrial pressure regulator depends on the application, including the process media, inlet and outlet pressures, flow requirements, temperature, required accuracy and materials of construction.

For general industrial pressure-reducing applications, Jordan Valve offers a range of regulator designs for steam, gas and liquid service. The Mark 60 Series, featuring Jordan’s sliding-gate technology, is commonly used where precise pressure control, fast response and long service life are important.

Higher-pressure applications may require a regulator such as the Mark 60HP, while applications with higher flow requirements or significant changes in demand may benefit from a pilot-operated regulator such as the Mark 67 or Mark 69.

Jordan pressure regulators are used across industrial process applications as well as steam systems in large commercial and institutional facilities.

Because regulator performance depends heavily on proper sizing, selection should be based on actual operating conditions rather than pipe size alone. Jordan Valve sizing tools and local representatives can help determine the appropriate regulator for a specific application.

Jordan Valve is a U.S. manufacturer of industrial pressure regulators and control valves for steam, gas and liquid applications. When comparing Jordan pressure reducing regulators with products from other manufacturers, consider both the regulator design and the requirements of your specific application.

Key factors to compare include pressure and temperature ratings, flow capacity (Cv), materials of construction, accuracy, shutoff performance, response to changing flow conditions, noise, maintenance requirements and expected service life.

Many Jordan pressure reducing regulators feature the proprietary sliding-gate seat design, originated by Jordan Valve in 1947. The short-stroke design provides fast response and precise control, while the multiple flow paths help reduce turbulence and operating noise. Jordan also manufactures other regulator designs for applications requiring different pressure, flow and control characteristics.

Lead time, replacement-part availability, technical support and application expertise are also important when comparing manufacturers.

Jordan Valve’s authorized sales representatives can review your operating conditions, size and select the appropriate Jordan regulator, and help evaluate it against other regulator options you may be considering.

Jordan Valve offers select industrial pressure regulators through its Quick Ship program, with popular configurations available to ship within five business days.

Quick Ship is available on select configurations of the Mark 50 Series back pressure regulator, Mark 60 Series pressure reducing regulator, and Mark 68G back pressure regulator. These options are ideal for customers who need to replace a regulator quickly, minimize downtime or meet an urgent project requirement.

Availability depends on valve size, materials, connections, Cv and other application requirements. Contact your local Jordan Valve representative to confirm Quick Ship availability and help select and size the appropriate regulator for your application.
