DFX Series electromagnetic pressure valve
一、 Purpose and structural characteristics:
DFX22 type, DFX23 type, DFX24 type electromagnetic pressure valve system two two-way, two-way and four-way spool valve structure two. It uses a DC or AC with a contact position double solenoid control slide valve to vary the flow direction of the oil flow.
The valve system is used to control elements of water, fire, power plants and other industrial sectors of the hydraulic system, also used as a high flow valve pilot valve.
The solenoid valve using packaged magnet, and the slide valve with magnetic orientation, cancel the mechanical lock, so that greatly reduced power solenoid-operated slide valve commutation, to ensure reliable operation. Coil according to long-term power design, so that the coil is not easy to burn. On each side there are two pairs of electromagnets sealed contact, in order to ensure that the solenoid is energized to work instantaneously. And issued a valve position signal corresponding work to facilitate remote control.
The valve auxiliary functional and equipped with manual button and doubles as a working valve position indication, even in the absence of oil pressure situations, but also to manual or automatic operation for easy inspection.
The valve structure is simple, at the same flow rate, compared with other same type of valve has a small and stable and fast operating power corresponding characteristic, applicable to computer monitoring system.

四、Installation, use and storage
After unpacking the valve, such as inspection found no abnormalities, the only check valve plug and body wash, generally do not have to break down. The valve must be installed horizontally, and the drain pipe joints (O) down the best, or at least at the site, so that the valve body can drain vent clean.
Before use of electromagnets insulation resistance should be checked and then press the system requires good line. When the solenoid valve with a DC power supply, you must press the icon "+", "-" pole wiring, otherwise the magnetic field generated by the coil is energized, the operation will have contacts magnet interference and affect the proper operation of the contact. Manual and automatic operation test, everything is working properly, can be put into operation.
Element if being not, should be injected into the internal anti-rust oil, and grease the exposed machined surfaces coated with anti-rust and stored in acid-free, alkali, salt and corrosive gases warehouse, from dust, rain and snow damage.
Users in custody, transportation, and comply with the conditions of use prescribed rules, from the date of shipment from the manufacturer or product two years in operation within a year (over period, whichever occurs first) due to poor manufacturing and damaged or not during normal operation, I plant responsible for maintenance and replacement.

3.Function Operation
The temperature unit commissioning instructions:According to the instructions take a good line, check and correct energized, the display window will show the measured value of the controlled object. Users should be set according to the actual situation, then use the (then press the button
, the setting items on the panel indicates the chart corresponding indicator lights.) Set operation is as follows:
1 press the button
, the indicator on the lower control panel lights, which can be set lower limit temperature Kai control point by ∧ or ∨ key, set the value in the digital display will show the window, after reaching the requirements, go to step (2) setting.
2 button at the lower limit of the control light is off
, the lower panel on the back of poor indicator lights, press ∧ or ∨ button to set back the difference (setting range 0 ~ 20 ℃), after the completion of this setting, go to step (3).
3 press the button
, the lower hysteresis light is off, then the upper limit of the indicator light on the control panel, press the ∧ or ∨ key to set the maximum temperature of Kai control point, after setup is complete, enter the first step (4).
4 Press the button
, the upper limit of the control lights off, and now back to the difference between the upper limit on the panel indicator lights, press ∧ or ∨ button to set back the difference (setting range 0 ~ 20 ℃), when you meet the requirements to enter the first step (5).
Note: The upper limit minus the upper limit of hysteresis can not be less than the lower limit value plus the difference between the lower back, otherwise the window will appear the words "RSET", will have to start again set in the normal display state.
5 Press the button
, the upper limit of hysteresis light is off, then the temperature correction indicator lights. Correction value has been set at the factory before, in general, do not modify this setting, in order to avoid the anti-amendment to the exact meter inaccuracies. When identified, including the control system includes a sensor error has occurred and can not get consistent results with higher precision level measurement device, you can use this product advanced "correction" feature, in order to reach agreement. (Setting: the temperature correction state, press ∧ or ∨ key to set the direction opposite to the one with the error to the same value within ± 10 range, the temperature values determined after the correction value displayed is the current temperature and the correction value and. if the current display temperature 26 ℃, tested high 3 ℃, the correction value can be set to -3, the revised display temperature 23 ℃;. whereas the opposite set) Press the button once
to set the operation is complete, the device enters monitoring status.
6 After the equipment operation, concrete work follows:
① When the value of the measured temperature is less than the lower limit, the corresponding heating load starts, the lower indicator light; when the temperature rises, the value of the measured temperature is greater than the lower limit value and hysteresis and corresponding heating load to stop, the lower light off。
② When the value of the measured temperature is greater than the upper limit, corresponding to the cooling load starts, ceiling lights; when the temperature decreases, the value of the measured temperature is less than the upper limit of the return of poor poor, the corresponding cooling load is stopped, ceiling lights off. (As shown below)

7 Product testing. If the meter displays "----", please check the temperature sensor is short-circuited or not connected. If the above situation the instrument will automatically start protection function, the temperature load supply cut off, shall be excluded in order to use the fault. If you find the instrument abnormal work, you should check whether the range of the sensor wiring broken or shorted or temperature sensing element lead-reverse, check the monitor operating voltage and ambient temperature working conditions are prescribed.
8 Break alarm. When a unit of the apparatus is active, if the corresponding break alarm indicator light, corresponding alarm output terminal is also in the closed state, then the load wiring is off, please check the wiring load! Humidity unit detects Description: In automatic state, mouth Kazakh gas, proximity condensation sensor (the sensor can not be directly immersed in the water) for about five seconds, humidity indicator lights on the monitor, the work load; away from moisture, light off, load stop working, indicating condensation sensor is not damaged. Such as humidity unit starts when the load is disconnected, the disconnection warning indicator light and humidity, humidity alarm output end there.
