5 Types of Air Flow Regulator Valve

5 Types of Air Flow Regulator Valve

Control Air offers three main types of air pressure regulators in various shapes, sizes, materials, and pressure ranges. All three subcategories boil down to precision controls. Filter slider and general-purpose controls In this post, we’ll go over some of the features and benefits of each category.

Industrial Pressure Control:

Industrial pressure-reducing regulators consist of an air flow regulator valve that is operated by a diaphragm, bellows, or spring-loaded piston. Downstream pressure works to push the diaphragm or piston in such a way as to allow or limit flow through the upstream valve to the downstream side of the low flow valve. Spring tension is adjustable for downstream pressure to maintain preset pressure. A change in downstream pressure automatically adjusts the valve to allow or limit fluid flow to a predetermined value. 

These industrial pressure regulators come in many forms. It depends on the manufacturer. It is the preferred choice in industrial environments for its durability and self-monitoring that applies system voltage without the need for power input or external sensing elements. It can be set on its own, AND the precision of the pressure control is sufficient for most applications. Variants of this design can use two air flow regulator valve that helps to ensure proper control in all conditions.

Solenoid Valve Controller:

Another way to control pressure. This is often used inside precision pressure regulators in calibration labs. Use an inlet solenoid valve, An inlet that allows supply pressure to enter the system, and an outlet solenoid valve to relieve atmospheric pressure or vacuum. The downstream part of the system is controlled by the addition or subtraction of gas molecules. Feedback data from the downstream pressure sensor is measured and processed by a control algorithm that opens and closes the air flow regulator valve to generate the final desired valve pressure setting.

For very precisely controlled pressure, Multiple inlet/outlet electronic flow control valves can be coupled with fine to coarse orifices that can be opened or closed depending on the difference between the set point and final pressure. And/or the rate at which the pressure approaches the set point. 

Needle Valve Regulator:

Another control method uses two precision-machined needle valves made of durable ceramic material that use small ports and threaded pistons. One air flow regulator valve supplies pressure and the other supplies exhaust pressure from the regulated downstream system. The valves are designed to provide fast and precise control. The modulating flow valve is controlled by an algorithm that continuously monitors the difference between the downstream pressure, the set point, and the rate at which the pressure approaches the set point. 

Piston Actuator Regulator:

They are generally used in hydraulic systems. The electric flow control valves work similarly to a deadweight tester by applying a force over the cross-sectional area of ​​the piston inside the cylinder. Pressure equals force divided by piston area, which is the definition of pressure P=F/A. The higher the pressure, the higher the pressure. The Mensor CPC8000-H uses this method to provide precise pressure control up to 23,000 psi. The benefit of this type of regulator is its ability to achieve very high pressures. This is achieved by reducing the cross-sectional area of ​​the piston.
