In many industrial scenarios, zinc-plated and nickel-plated magnets have been widely applied. The valve industry is a typical example. Zinc-plated and nickel-plated magnets have certain applications in valves, mainly including two types: switch-type and proportional-type.
The switch-type zinc-plated and nickel-plated magnets are mainly used for the reversing of reversing control valves, the unloading and loading of systems, and so on. The proportional-type zinc-plated and nickel-plated magnets are mainly installed on various proportional valves and are often employed to control the direction, pressure, and flow rate of fluid flow.
Here is a detailed introduction:
Many proportional pressure valves are installed on electronically controlled variable pumps to control the flow rate and direction of the pumps. Proportional-type zinc-plated and nickel-plated magnets also have the characteristic that the electromagnetic force remains almost unchanged within their stroke range, which distinguishes them from ordinary switch-type zinc-plated and nickel-plated magnets. Moreover, this main characteristic of suction is formed through the special shape of the working air gap and the guidance of the magnetic force of the magnetic conductor.
The difference between switch-type and proportional-type zinc-plated and nickel-plated magnets does not entirely depend on the magnets themselves. When the proportional-type zinc-plated and nickel-plated magnets are at the maximum current, they are equivalent to switch-type zinc-plated and nickel-plated magnets. Meanwhile, switch-type zinc-plated and nickel-plated magnets will also generate different thrusts under different currents.
Then, they can be generally classified according to voltage, such as 12V and 24V direct current, and 110V and 220V alternating current, etc. For the zinc-plated and nickel-plated magnets used in NG6 solenoid valves, the pushing (pulling) force is usually between 20N and 70N, and the stroke is between 3mm and 7mm. Therefore, once we suspect that a solenoid valve is stuck or its coil is burned out, we can judge by checking whether its stroke is within the above range.
The performance indicators of zinc-plated and nickel-plated magnets mainly include applicable voltage (current), pushing (pulling) force, and stroke, etc.
The above is the detailed introduction of the application of zinc-plated and nickel-plated magnets in valves. We hope it will be helpful to you.
