DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve
Description: DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve is mainly used in coal mines and mines. Controls pneumatic components such as double-acting pneumatic heads, cylinders, air motors, pneumatic actuators, etc. The valve is a pilot-type dual electronically controlled pneumatic circuit conversion structure.
DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve is mainly used in coal mines and mines. Controls pneumatic components such as double-acting pneumatic heads, cylinders, air motors, pneumatic actuators, etc. The valve is a pilot-type dual electronically controlled pneumatic circuit conversion structure. When the power is turned on, the normally closed path is changed to normally open, and the normally open path is changed to normally closed. The gas path is restored when the power is turned off. (can also be used as a two-position three-way)
DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve works
DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve is a dual-purpose solenoid valve. Is off state. At this time, the intake pressure of the intake port 1N pushes the small piston, the intake port 1N communicates with the working port 1, and the working port 2 communicates with the exhaust port 2. When energized, the moving iron core is sucked up by the electromagnet, and the pilot valve is opened to push the intake pressure to push the large piston. The valve stem is moved under the pressure difference between the large and small pistons, so that the air inlet 1N communicates with the working port 2, and the working port 1 communicates with the exhaust port E1. After the power is turned off, the pilot valve is closed because the moving iron core is restored to the initial position by the spring pressure.
Installation and use of DFB-8-SH-1.0 double electric control two-position five-way mine explosion-proof solenoid valve
1. Before installation, first purge the pipeline to prevent the welding slag and other objects from damaging the sealing surface.
2. When installing, it is necessary to determine the normally open and normally closed working ports. Working port 1 is a normally open working port, and working port 2 is a normally closed working port.
3. Install according to the mark and number on the valve body.
4. The conditions of use are in accordance with the technical specifications.
5. Explosion-proof products, please connect the leads according to the relevant requirements of explosion-proof requirements.
