What is a pressure regulator? The major purpose of a regulator is to match the flow of the medium which could be gas, steam, or liquid through the regulator according to the requirement of the medium for the system. It would keep the system pressure at the required pressure and thus would control the overpressure …

There are two basic categories of diaphragm elements: rigid metal diaphragms and slack diaphragms linked to driving plates. Schaffer gauge The simplest form of diaphragm gauge is the Schaffer gauge, shown in above figure. It consists of a corrugated diaphragm of about 65 mm in diameter heat treated stainless steel and held between two flanges. …
Fluid pressure can exert in the storage tanks, as described by the formula F = PA. One practical consequence of this is that process vessels and pipelines can burst catastrophically if they are subjected to excessive fluid pressure. Some vessels and piping may implode if they are subjected to excessive vacuum (collapse on themselves). These …
Micro-Electro-Mechanical Systems, or MEMS, are technologies that are in the most common form that can be defined as miniature mechanical and electro-mechanical elements (i.e. devices and structures) made using microfabrication techniques. the types of MEMS devices can vary from relatively simple structures having no moving elements, electromechanical systems to very complex with multiple moving elements …
Main pneumatic components All main pneumatic components can be represented by simple pneumatic symbols. Each symbol shows only the function of the component it represents, but not its structure. Pneumatic symbols can be combined to form pneumatic diagrams. A pneumatic diagram describes the relations between each pneumatic component, that is, the design of the system. …

What are the dryers? Compressed air dryers remove moisture that might otherwise condense in airlines, air tools, and pneumatic instruments. This condensate can cause damage to equipment from corrosion, freezing, and water hammer, and can cause malfunctioning of instruments and controls. Three types of air dryers are available: adsorption, deliquescent, and refrigeration. Types of Dryers: …
Introduction This Pressure Reducing Valve is an elastomeric, line pressure driven pilot operated pressure control valve. Designed specifically for advanced fire protection systems and the latest industry standards. This Pressure Reducing Valve reduces high upstream pressure to a precise, preset, stable downstream pressure. Due to its exceptional reliability and low head loss the valve is ideal …
Introduction The flapper nozzle is the primary device for all pneumatic instruments which convert a measurement to a pneumatic signal. Figure shows the layout of the device.  Principle of Operation: The air supply input (20 psi (1.4 bar)) passes through a restrictor (small hole). It then goes out of the nozzle or down the air …
Mechanical Pressure transducers: In general, transducers are devices which converts one form of energy into another form, a pressure transducer converts pressure into any other measurable form of energy. A mechanical pressure transmitter converts the pressure into mechanical displacement in the system. Types of Pressure transducers: Bourdon tube Helix and spiral tubes Spring and bellows Diaphragm …
Pressure reducing valve is a type of pressure control valve. This type of valve is used to maintain constant reduced pressure in a pipeline where the flow is fluctuating. This type of valve (which is normally open) is used to maintain reduced pressures in specified locations of hydraulic systems. The high incoming pressure is reduced …
