  • Compressed Air Systems Technical Data
    When air is compressed in a tank system, water accumulates in the tank. To understand how this works, think of a stack of sponges saturated with water. Exert pressure on the sponges and water comes out. Compressing volumes of air has the same effect. The humidity in the air accumulates in the tank
  • Butterfly Valves in Compressed Air & Vacuum Services
    . If they do, and the application is a low pressure one, about 50 PSI or less, the Hayward butterfly valve should do the job. One thing to remember though is that the soft elastomer liner of the butterfly valve will have a tendency to dry out and harden in compressed air or gas service. This will make

    Summary of Pressure Sequence The sequence of compressed air flow in a pneumatic system is shown again in Fig 28: * Air Compressor - outside air is compressed to a pressure higher than that of the atmosphere. * Air Line Conditioners - devices located at various points provide moisture removal

    with the. media, which can include motor oil, brake fluid, refrigerants, hydraulic. fluids, seawater, wastewater, tap water, oxygen, compressed air, and. nitrogen, to mention just a few. Special consideration must be made for. harsh media such as ammonia, ionized water, salt water, hydrogen,. acids and jet fuel
  • A Pressure Transducer that Can Handle Just About Anything
    : Beginning at the compressor, the refrigerant is compressed and leaves the compressor as a high temperature, high pressure gas. Step 2: The hot refrigerant enters the condenser, which is usually fan forced air cooled; then the refrigerant leaves the condenser as a warm liquid and continues

    is weakened intentionally. The degree of deflection caused by the pressure is measured using metallic strain gauges. Usually four strain gauges are applied to a diaphragm. Some of them are located on elongated areas of the diaphragm and others on compressed areas. If the diaphragm deflects under the action
