The use of electronic mixers is compulsory in places requiring special precautions, such as hospitals and public places. By moving the hands in the infrared area of taps or approaching shower and urinal systems, water will flow. Important: The use of a timer operated solenoid valve competes with a more refined and much more expensive system based on a zero loss timed electronic drain with no waste of compressed air.Įquipment for supplying water without hand contact. Since this is a direct acting valve with a rather small orifice (2.2 mm) it should be fitted with a filter to prevent condensate from clogging the valve. The recommended valve combines small dimensions and performances suitable for use with compressed air (0-15 Bar). A warning light notifies problems in the exhaust system. The control panel operates a solenoid valve so that only the condensate produced is drained and expensive losses of compressed air avoided. The level of condensate in the tank is controlled by a level sensor connected to the control panel. The valve prevents the temperature in the evaporator from going down and consequently the condensate from freezing. Cold produced by the refrigerating system adjusts to the temperature and flow rate changes of compressed air thanks to a by-pass valve with “hot gas”. The refrigerating circuit produces cold needed to cool compressed air to Dew Point (2☌ – 3☌). The condensate produced during the cooling process is set apart and drained before leaving the system, compressed air is heated in the air-to-air exchanger mentioned above. Inside an air-to-air exchanger, compressed air going into the system is precooled by dried compressed air coming from an evaporator then it enters the evaporator where it is cooled down to Dew Point by the evaporating frigorific medium (freon). The diagram below shows a typical installation of an air dryer in an industrial system for air treatment: (1) Air Compressor (2) Cooler (3) Separator (4) Tank (5) By-pass Valve (6) Dryer. In the most common applications about 70% of water is eliminated by the final cooler, whereas for the remaining 30% only an air dryer is effective. Compressed air produced by compressors contains a large quantity of steam that can condensate and provoke serious damage in the equipment utilizing it. In their typical application, air dryers are used to remove the condensate in compressed air installations.
The body of the recommended valve is nickel coated to protect the brass against corrosion when detergents flow through it. The solenoid valve used in this application is: Usually, water used for rinsing is softened and osmotic, a treatment that prevents white limescale from staining the vehicle. The lance is a washing gun shooting either water or shampoo under pressure, according to the selected cleaning cycle. Before reaching the brush, the liquid is further mixed with air. Three more solenoid valves inside the circuit intercept liquid detergent, foam and wax respectively and mix them with water.Īn electromechanical pump sucks up the mixture by depression and lets it back into the circuit at 80 bar. During the shampooing cycle, two solenoid valves let cold and hot water into the circuit. While the vehicle is being rubbed, the brush pours liquid detergent to remove dirt. The user selects a cleaning cycle on the control panel and cleans the vehicle using two basic tools: a lance and a brush. The system delivers high-pressure water mixed with wax, detergent and car washing foam through a lance and a brush. They are self-service washing areas for cleaning vehicles like scooters, motorcycles, camper vans, caravans, small boats and all-terrain vehicles that cannot be cleaned in traditional car washing systems with brushes. Self-service car washing systems are an innovation in the car washing field.
The applications that some of our solenoid valves have been used in are as follows:
Asr valve cascadia.Solenoid valves have a wide variety of uses in water applications.
