Control Solenoid Valve Capable of Producing an Output of Working Fluid

Festo launches a new series valve jet, said extremely fast switching time of less than 1 ms - an order of magnitude faster than the standard setting solenoid valve. Based on a new design with only one moving part,high pressure filters the new set of valve jet MHJ is also very high switching time,propane high pressure regulator repeatability, and claimed to have been a sign of life 10 billion.

The jet valve adapted to different applications of sorting a large volume, particularly in food processing and recycling industry. Festo valve jet HJ series is designed for use with 40um standard designed filtered air, and host a wide range of operating pressures of 0,5 bar at 6. They offer a choice of three switching 2/2-way model quickly with flow rates of 50, 100 and 150 liters per minute.

The valves use a special short plate valve developed and patented a decay CAE full modeling of magnetic tape in order to optimize the temperature and flow behavior changes its characteristics. To go so fast, that offers long life, the new design does not require dynamic seals and lubrication. The design of the magnetic coil and amortization flat plate also allows the valve to the constant replay of the conversion is less than 0,1 ms for the duration of specialist machinery for the sorting is necessary.

HJ Jet Series valves have a voltage range of the signal starts from 3 to 30V DC, to receive the standard 5V PLC signals without the need to convert the voltage. The valves have a power consumption of 7W, which can be reduced to 2W, the first time using a switch control fixture that can be provided by Festo is embedded in the coil assemblies or within Council control applications.

Festo HJ Jet Series valves are available in single units with an integrated and accessories can be provided on the structure of the sliding plate with sub-bases. Festo also produces custom headers that allow groups of air valves with the same hand that can be fixed nozzle, if necessary.

As is well known in the art, control valves have frequently been used to control and supply a working fluid, such as air, to a working device. Typically, these control valves employ a moveable valve spool disposed in a valve housing. The valve housing includes a plurality of fluid passages that are selectively interconnected in response to movement of the valve spool so as to control the flow of the fluid and, thus, the output of the control valve.

Conventional control valves often employ a solenoid valve mounted thereto for actuating the valve spool. The solenoid valve is controlled via an electrical input signal between a first position, where the solenoid valve is de-energized so as to close a fluid passage between an input pilot pressure and an output controlling pressure and to open the outlet to atmosphere, and a second position, where the solenoid is energized via the electrical input so as to open a passageway between the input pilot pressure and the output controlling pressure and block the fluid passage from outlet to exhaust.

It should be readily appreciated to one skilled in the art that in order to apply a constant controlling pressure, the electrical control signal must continue to energize the solenoid valve. That is, in order for a conventional control valve to maintain the spool in a predetermined position, it is necessary to maintain a constant control pressure upon one side of the spool. Therefore, in order to maintain this constant control pressure on the spool, it is necessary to maintain the solenoid valve in an opened and, thus, energized state. Moreover, it is necessary to employ full line fluid pressure to displace and maintain the working device in a predetermined position. Therefore, it will be understood that operating a device at full line pressure requires more energy to drive compressors than operating the device at a reduced line pressure.

Accordingly, there exists a need in the relevant art to provide a control solenoid valve capable of producing an output of working fluid to be used with a conventional working device that is capable of minimizing the energy consumed during actuation. Furthermore, there exists a need in the relevant art to provide a control valve that maintains the position of a control element at a pressure less than full line pressure. Still further, there exists a need in the relevant art to overcome the disadvantages of the prior art.
