Pressure regulators are an essential part of flow control mechanisms. The purpose of the pressure regulator is to adjust to flow rate, thus having an effect on pressure as well. The orifice which the liquid or gas must pass through is a certain diameter. If the material flows are reduced, the pressure will be lower. If the flow is increased, then the pressure will be higher.Flow regulators are used more often for liquid applications and pressure regulators are often more predominant with compressible gases. Because gas can be condensed it is often more difficult to control than a liquid. That is not say that this is always the case, but in general, pressure regulators are generally associated with gases. However, some applications use pressure regulators for liquid applications. The differences in physical characteristics of the gas or liquid that is being used.

Even among gases, various elements and mixtures have various levels of compressibility. Some gases can be compressed to hire pressures than others, which has a significant impact on the pressure regulator or flow regulator that is chosen. A proper pressure regulator will allow enough gas to flow through to build up the pressure to the required PSI, regardless of the flow rate. KPI makes a high flow precision pressure regulator with a single valve design. The response time is less than 250 milliseconds. This allows for more consist in output rate. This fast response time allows it to work in a dynamic environment, without slowing down the production process. Response time is the key to consistent and highly production line manufacturing processes. In applications such as welding, fast response time is essential for consistent results. KPI also makes a low flow precision regulator with a dual proportional valve design. It is designed specifically for low volume flow rates.

It can sustain both positive and negative outlet pressures and it is an improvement over dual on/off valve electronic regulators. An optional digital display is available with this model. It can provide electronic performance feedback as well. Input can be controlled either manually from a remote control device. It provides continual electronic performance feedback. It has an optional digital display available, a 50 micron filter and a gauge. Like all of Kelly Pneumatics products, the filter can operate with a variety of mediums including water, air, and other non-corrosive liquids and gases. It is 50 micron to allow filtration of most particulates. The inline gauge is compatible with a number of Kelly's products. Versatility and customize ability are the key assets that set Kelly Pneumatics products apart from their competitors. Performance and reliability are the key to maintaining highly productive manufacturing processes and reducing the number of reworks and quality control rejects. Kelly Pneumatics offers a wide variety of products including pressure regulators and flow regulators, as well as mass flow controllers and a variety valves.
