Pneumatic Regulators

Pneumatic regulators, also known as pressure-reducing valves, are used in pneumatic systems to maintain the output air pressure. They are commonly used in pneumatic air compressors. Pneumatic regulators can provide a quick response and accurate pressure regulation for even the most demanding industrial air preparation applications. They make sure that compressed air in a pneumatic system is not wasted.

How does a pneumatic regulator work?

Pneumatic regulators maintain output pressure by automatically cutting off the flow of a gas or liquid when it’s at a certain pressure. Most regulators use simple wire coil springs to control the pressure.

When installing a pressure regulator, it's important to choose one that is appropriately sized for your particular system. If it's too large it will increase air usage and waste energy. So ensuring the proper sizing and setting of your pressure regulator is crucial for efficient air consumption.

Where are pneumatic regulators used?

Pneumatic regulators are found in many common home and industrial applications, including heating furnaces and gas grills as well as in medical and dental equipment. They're ideal when pressure must be closely controlled, as is the case when dealing with gas.

Things to consider when choosing a regulator:

  • Inlet pressure
  • Outlet pressure
  • Connection port sizes
  • Flow rate
  • Operating temperature
  • Size and weight requirements
