Back Pressure Regulators

Jordan Valve has a large line of back pressure regulators designed to meet diverse specifications and applications, including steam, liquid, and gas.

Our upstream pressure regulators are available in different models including,

• Self-operated
• High-flow
• Differential
• Vacuum
• Air-loaded
• Pilot-operated

Many of our back pressure regulators feature sliding gate technology, providing precise control, reliability, and accuracy not found in other valve designs.

For assistance choosing the right back pressure regulator for your application, use our sizing software program or contact your local representative.

How Do Back Pressure Regulators Work?

A back pressure regulator maintains a constant inlet pressure by sensing upstream pressure and adjusting its opening or closing to control the flow. When fluid pressure at the inlet of the upstream pressure regulator exceeds the setpoint, the regulator opens to relieve the excess pressure. It continually adjusts its position to keep the inlet pressure at the desired setpoint.

In the normally closed position, upstream pressure is sensed underneath the diaphragm. As upstream pressure increases above the setpoint, the pressure of the service overcomes the spring force and begins open the valve. This bleeds off the pressure on the upstream pressure side and maintains the constant upstream pressure.

Benefits of Using Back Pressure Valves

Some of the benefits of using back pressure valves include:

• Straight-through flow where turbulence is reduced and superior trim life is achieved.
• Our sliding gate design provides exceptional low flow control since the flow works with the seat and not against it.
• Short stroke with fast response. The stroke length is typically ⅓ that of a globe valve, reducing the amount of droop (deviation from setpoint) in the regulator.
• A variety of seat coatings and seat materials to meet almost any application. The Jorcote seat is standard and delivers outstanding performance.
• The sliding gate design provides an area of closure, not just a line of closure. This area of closure reduces the effects of wire draw which is the most common cause of seat leakage.
• Less maintenance and downtime, and more opportunity to increase yields and profits.
• Easy maintenance. Your flow requirements change, and interchangeable Cv’s are available.
• The movement of the sliding gate seats generates a self-cleaning action.

Frequently Asked Questions

1. What is a back pressure regulator?

A back pressure regulator is a device that maintains a defined pressure upstream of its inlet. In other words, it controls the inlet pressure while allowing any excess pressure to vent through the regulator.

2. What’s the difference between a pressure regulator and a back pressure regulator?

Back pressure regulators perform the opposite function of pressure regulators. It is normally closed while a pressure reducing valve is normally open. Secondly, the back pressure regulator controls upstream pressure, while a pressure reducing valve controls downstream pressure.

3. How do you install a back pressure regulator/valve?

A back pressure regulator/valve controls upstream pressure and is installed at the end of the line (unlike a pressure regulator that controls outlet pressure and is installed at the beginning of the line).

4. How do you adjust a upstream pressure regulator?

To adjust a upstream pressure regulator you just need to adjust the screw at the top of the valve. You can tighten or loosen the screw.
