Product introduction: ZQDF(Y) series steam (liquid) solenoid valve is an actuator used in industrial process automation control system. It can automatically open or close the valve after receiving the electric control signal to realize the on-off or flow adjustment control of the fluid medium in the pipeline. , So as to automatically adjust or remotely control the temperature, flow, pressure and other parameters in the system. ZQDF series steam solenoid valves can be widely used in production and scientific research departments such as textiles, printing and dyeing, chemicals, plastics, rubber, pharmaceuticals, food, building materials, machinery, electrical appliances, and surface treatment, as well as in people's daily life facilities such as bathrooms, canteens, and air conditioners.

Installation instructions:
1. When installing, the solenoid valve coil should be upward and keep the vertical position. The arrow or mark on the solenoid valve should be consistent with the flow direction of the pipeline. It should not be installed where there is water splashing or water leakage.
2. The working medium of the solenoid valve should be clean and free of particulate impurities. The dirt and filter on the surface of the solenoid valve internals must be cleaned regularly.
3. When the solenoid valve fails, in order to isolate the solenoid valve in time and ensure the normal operation of the system, install a bypass device. Note: The valve on the bypass must be closed at ordinary times. If the solenoid valve is installed on the bracket, the diameter of the solenoid valve should be smaller than that of the valve on the main pipeline.
4. Before installing the solenoid valve, the pipeline must be cleaned. It is recommended to install a filter in front of the valve and install a trap in the steam pipeline.
5. Do not install the valve in the recessed part of the pipeline, so as not to hinder the action due to the precipitation of steam, condensate, impurities, etc. in the valve.
6. Ordinary type cannot be used in explosion hazard situations.
7. In the case of insufficient pipe rigidity, it is recommended to fix the pipes before and after the valve with brackets to prevent vibration caused by the solenoid valve during operation.
8. Before installation, pay attention to read the product label, carefully read the instruction manual, and judge whether the product meets the conditions of use.
9. Pressure gauges should be installed on the pipes before and after the solenoid valve to observe the pipe pressure.
Use and maintenance:
1. It is recommended that the user unit appoint a person to be responsible for use and maintenance.
2. After the solenoid valve is installed, it must be tested for several times with the medium, and then it can be put into formal use after confirming that it is normal.
3. The dirt on the inside and outside of the large valve and the suction surface of the armature should be cleaned regularly. Be careful not to damage the sealing surface.
4. When the solenoid valve is not used for a long time, the manual valve in front of the valve should be closed. When it is reactivated, the steam solenoid valve should drain the condensed water and make a trial operation several times. It can be put into use after the switch is normal.
5. When the solenoid valve is removed from the pipeline and not in use, the internal parts should be tested clean and blown with compressed air for storage.
6. When using for a long time, if the seal between the piston and the valve seat is not good, the sealing surface of the piston can be ground again, and then ground with the valve seat.
7. When working, pay attention to the pressure gauges before and after the valve. The working pressure must not exceed the rated pressure, and the working pressure difference must be within the range of the rated pressure difference. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped and the front and rear manual valves should be closed to prevent the solenoid valve from exploding and leaking.

200X pressure reducing valve is a kind of valve used for parallel connection of fire water and domestic water in the water supply system, used to allocate the direction of water supply.
Check valve can regulate the opening and closing speed. When the pump starts or stops running, it can be adjusted to the best opening or closing speed with the on-site adjustment.It is suitable for mining enterprises and high-rise buildings to reduce water hammer and water hammer in direct water supply and drainage system by water pump, so as to achieve the effect of safe closing.
The 500X relief/hold valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or to maintain pressure in fire fighting water supply systems.
400X flow control valve is a kind of valve used to allocate the direction of water supply in parallel water supply system for fire protection and domestic use.
The 600X electric control valve is a hydraulic operated valve with solenoid valve as the guide valve.
700X water pump control valve is a kind of reverse valve installed at the outlet of water pump in high-rise buildings and other water supply systems to prevent the backflow of media.
Flange pressure reducing valve from the general thread of the pressure reducing valve, its connection flange, this is a control valve in the body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, under the condition of the inlet pressure changing, keep the outlet pressure within the scope of the set, protection appliances for production from then on.
Model 200P pressure reducing valve is a direct acting type adjustable pressure reducing valve, using diaphragm type hydraulic operation, can be installed horizontally or vertically in water supply, fire fighting system or other clean water system.
