If there is a change in the controlled pressure, the diaphragm will be forced to move. For example, the pilot plug will allow upstream gas to flow under the diaphragm where the pressure is controlled by the position of the plunger. If any pressure exceeds your set point, the pressure below the diaphragm will be pushed up, closing off the pilot plug.

We have a variety of pressure reducing regulators available, including self-operated, high flow, differential, vacuum, air-loaded and pilot-operated. Many of our pressure reducing valves have the sliding gate technology which offers precise control in a variety of applications.

Pressure reducing regulators are used to maintain a set downstream pressure point by reducing the supply, also known as inlet pressure, of a fluid or gas to lower the outlet pressure.

Pressure reducing regulators monitor the downstream pressure and do not need any external power or air source to operate. Instead, they work by force balance. There are 4 main parts to a pressure regulator:

Our regulators are designed for applications demanding highly accurate pressure control and reliable set point accuracy.

However, the most important things you’ll need to know in selecting a regulator for a specific application are what the flowing media is and what the desired flow rate is, and what the inlet and outlet pressures will be.

The compressed spring and diaphragm are the two opposing forces and the plug acts as the balance between the two. The set screw is used to show the regulator how much pressure we want by turning it to compress the spring. A compressed spring generates a force causing it to push down. This opens the plug and results in more flow (of water, air, or other media).

Jordan Valve has a large line of pressure reducing regulators to meet many different specifications and applications, from self-operated to pilot-operated. The sliding gate pressure reducing regulators achieve levels of performance, reliability and accuracy that are not found in other valve designs. Request a quote today.

The PAX1 is ideal for midstream and downstream natural gas systems demanding precision and reliability, such as natural gas distribution automation.

Fairchild, a Rotork brand, manufactures a full range of market-leading regulators, boosters, relays and transducers. Our products are used in applications that require precision control of pneumatic devices and motion control equipment.

How you choose a pressure reducing regulator depends on why you need it. There are five things you need to have to choose the right pressure reducing regulator with the right flow coefficient (Cv):

Our sliding gate pressure reducing regulators are ideal for steam, liquid and gas media applications. However, we also see use cases for the following applications:

After you have correctly sized your regulator, you’ll then need to know the line size, material, type of connection, whether it’s a shutoff or not, and if it’s either direct or pilot-operated.
