  Air Pressure Regulator start, stop or change the direction of flow in compressed air applications. They are one of the most fundamental parts in hydraulic machinery as well and pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. The movement of the spool restricts or permits the flow, thus it controls the fluid flow. Many manufacturers apply compressed air as the power to operate tools and equipment which are used to make the products they offer. To understand the different applications of compressed air and how valves are used, one must first have a knowledge of the kinds and types of valves used by industries.

  Linear Valves

  Linear valves are simply designed and easy to maintain. They are also extremely versatile, offering a wide range of pressure classes, sizes and design options. Linear valves are typically more expensive, usually using pneumatic or hydraulic actuators. However, they are also more resistant than rotary valves to cavitation, erosion and excessive noise. They tend to operate more slowly, but have greater accuracy and positional stability of the closure element. Linear valves can be cage-guided, stem-guided or top/bottom-guided.

  Linear Angle Valves

  Linear angle valves are a type of globe valve where the inlet and outlet ports are situated at right angles to each other, and are often used in tight spaces. In this type of valve, a closure element – a slat, a disc or something flexible like a diaphragm – is moved in and out of the angled valve seat by means of a linear actuator. The valves can be cage-guided or stem-guided, and have a range of design options. These include restricted trim, expanded outlet connections for low-flow applications, and outlet liners that help to resist damage. They are best suited for more demanding applications, where noise, large flow rates and flashing can be more easily mitigated with appropriate technology.

  Linear Globe Valves

  Linear globe valves are a popular choice for their noise-mitigating properties, their ability to regulate a wide range of flow requirements, and their internal accessibility which allows easy maintenance. A spherical body typically contains a stationary ring seat with a cylindrical or disc-shaped plug element. These valves are available in all design styles, with top/bottom-guided and stem-guided valves being more suitable for general industrial purposes and less demanding applications. Cage-guided valves perform well in a wider range of applications, and can be fitted with mitigating features for noise and cavitation, but they tend to be more expensive. All types of globe valve can be controlled by all modes of actuation, making them a great deal more versatile.

  Three Way Control Valve

  Linear 5/2 Way Pneumatic Valve are commonly used in industrial applications, and have a combination of one and two inlets and outlets, which enables one-into-two fluid separation or two-into-one mixing. This type of valve is usually cage or stem-guided, and is used to control the amount of pressure or flow in between two sections of the piping system. Typically, this valve is not used in very demanding applications, being more suited for things like boilers, water chillers, fan coils and air-handling units.

  Rotary Valves

  Rotary valves regulate flow by rotating one or more passages in a transverse plug. They can incorporate a wide variety of adaptive technology, which makes them very versatile. They typically offer a less tortuous inline path than linear valves, while still providing similar rangeability, flow control and severe-system resilience. Their design is inherently advantageous to applications with actuating fluid which may contain particulates and can't be kept scrupulously clean.

  In addition to the above-discussed tips, you can discuss your requirements with the manufacturer.
