The solenoid valve is used in the liquid path system to realize the on/off of the liquid path or the change of the flow direction. It generally has a valve core that can be driven by the electromagnetic force of the coil. When the valve core is in different positions, the passage of the solenoid valve It is different. There are several working positions of the valve core. The solenoid valve is called a few solenoid valves: the interface on the valve body, that is, the number of passages of the solenoid valve, there are several passage ports, and the solenoid valve is called a solenoid valve.
About the problem supplement
After the solenoid valve is installed, generally all the interfaces should be connected. The so-called working position refers to the position of the spool. The valve core is in the position A when the coil is not energized, and is in the position B when the coil is energized, and the valve core is in the different positions to play or close or close the interface. The two-person name has not been heard, but it should be possible to understand a few passes.
The panels and quoins are made of natural stone, quartzite, granite, limestone, sandstone or slate. Each panel is composed of a number of individual natural stones that have been dressed by hand and adhered together with a cement back reinforced with a light metal or fibreglass mesh. All panels and quoins are Z-shaped in order to hide the joints from view, therefore, creating an authentic stone wall appearance each time.
Made from natural stone, our panel systems improve in colour and maintain the beauty and characteristics in all climates, therefore the perfect alternative to manufactured stone and traditional methods.
