Solenoid valves are equipped with a dry magnetic rotor and a conical seat valve. In their initial state, the valves always are open to the return line and are activated by a return spring. The current switching positions remain as long as current is switched on. Solenoid valves are switchable and resistant to compression in both flow directions.
Dry Erase Clear Gloss Coating is a two component, waterbased polyurethane, for use over prepared interior surfaces where a dry erase surface is needed. Allows standard dry erase marker writing to be removed using a dry cotton cloth or dry eraser.

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets ...

A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 199 In Figure 2a, the WHIMS is used after conventional gravity concentration to remove a magnetic stream that can be upgraded easily to finished-product ilmenite. The resulting non-magnetic fraction is then further upgraded by gravity concentration, and followed by conventional dry
Dry erase supplies are also offered, with pens, markers and erasers to replenish stores. Being able to use and reuse a magnetic board, magnets and other items means being able to re-purpose or re-design a system for a business that is in the state of evolving.

The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field.The magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earth's North magnetic pole ...
Sep 15, 2019· How to Restore a Whiteboard. Don't throw old whiteboards away. This article describes how to restore dry erase whiteboards that have become hard to erase and/or require constant cleaning. While it's very difficult to get the board back to...
Magnetic pull-off gages use a permanent magnet, a calibrated spring, and a graduated scale. The attraction between the magnet and magnetic steel pulls the two together. As the coating thickness separating the two increases, it becomes easier to pull the magnet away. Coating thickness is determined by measuring this pull-off force.
Jun 03, 2019· To erase old marks off a dry erase board, wet a sponge with rubbing alcohol and rub it onto the stain, wiping the area clean with a dry cloth. If you don't have rubbing alcohol, draw over the old stains with a new, dark colored dry erase marker, and erase as you normally would. It might take a few tries to remove the mark with this method.
The flow principle behind magnetic flow meters is known as Faraday's Law, mathematically defined as E=k*B*D*V. The induced voltage (E) is directly proportional to the velocity (V) of the fluid moving through the magnetic field (B). The induced voltage is carried to the transmitter through the electrode circuit.
