GADP17E Pressure Reducing
valve is supplied as for the GADP17 with a control spring but the maximum pressure is limited to 10 Bar g due to the addition of the
Solenoid Valve. A solenoid operated valve is fitted in te pipe between the pilot valve and the main diaphragm camber and is thus in series with the normal pilot valve.
The purpose of the solenoid valve is to override the pilot valve thus causing the main valve to shut-off. It can be controlled by any device capable of interrupting the supply of current to the solenoid coil.
The dolenoid is arranged to open the valve when the coil is energised so that whatever switching device is used it must be arranged to break the current to close the main valve. In this way the unit will always fail-safe i.e. will close the main valve in the event of a failure in electrical supply.
Electrical supply
It is important that the solenoid is connected to the correct voltage. Therefore always check on the supply details which are stamped on the solenoid valve name-plate before attempting to connect up. Electrical connection is by cable plug to DIN 43650. All wiring, cnnectors, etc. in close proximity to the valve should be of heat resisting type and comply with local and national electrical codes.
This pilot operated reducing valve is the new type pilot extra-huge membrane pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.
Another outstanding advantage of the valve is: a valve body can be installed with many pilot valves, to realize the temperature control,
upper stream pressure control and long-distance switch control as well as pressure regulating.
