Powerful magnets have certain applications in valves. They mainly include switch type and proportional type. Among them, switch type powerful magnets are mainly used for reversing control valves, unloading and loading of the system, etc. The proportional powerful magnet is mainly installed on various proportional valves and is often used to control the direction, pressure and flow of the liquid flow. Many proportional pressure valves are installed on the electronically controlled variable pump to control the flow and direction of the pump.
In addition, the proportional strong magnet also has the characteristic that the electromagnetic force within its stroke remains almost unchanged, which can be distinguished from the ordinary switch-type strong magnet. In addition, the main characteristic of this attraction is formed by the special shape of the working air gap and the guidance of the magnetic force of the permeable magnet. The difference between switch-type and proportional-type strong magnets is not entirely dependent on the strong magnet itself. When the proportional-type strong magnet is at the maximum current, it is already equivalent to the switch-type strong magnet, while the switch-type strong magnet is at the same time at different currents. Different thrust will also be produced.
The performance indicators of powerful magnets mainly include applicable voltage (current), push (pull) force and stroke.
