Air flow regulator vs pressure regulator.

Regulators are used for gases and liquids and can be an integral device with a pressure setting a restrictor and a sensor all in the one body or consist of a separate pressure sensor controller and flow valve.

A simple example of a pressure reducing direct operated regulator design compared to a control valve in a control loop is shown in figure 1. Placing the regulator before the valve in a pneumatic system ensures that the regulator will not be cycled or exposed to reverse flow.

Pressure regulators are not designed to control flow rates. Although pressure regulators used in flowing systems inherently affect the flow by controlling the pressure they are not designed to act as flow controllers. A pressure regulator is installed before a valve to allow a pre set pressure to flow downstream to a cylinder or other volume.

Parker offers a range of miniature economy compact standard hi flow and pilot operated regulators to meet a range of service needs. Air regulators provide quick response and accurate pressure regulation for the most demanding industrial air preparation applications. These types of air pressure regulators see a lot of use in the fluid power industry as well as process control instrumentation and panels. For example if your shop air is 90 psig but your valve rating is 60 psig a piston regulator is useful to knock the.

The pressure regulator allows the user to adjust the air compressor pressure depending on the air tool being used. Any change in the controlled pressure causes the diaphragm to move which causes the flow area of the regulator to change allowing more or less process fluid through the regulator. This phenomenon is known as droop. The resulting graph shows the drop in outlet pressure as the flow rate increases.

The accuracy of a pressure regulator is determined by charting outlet pressure versus flow rate. Pressure regulator accuracy is defined as how much droop the device exhibits over a range of flows. Since they are more economic they make good units to regulate individual service lines rather than the main shop airline which would require a unit with a greater flow allowance. A pressure regulator is a valve that controls the pressure of a fluid or gas to a desired value.
