Permanent Magnets for solenoid valves
Great engineering tool that can replace the electro magnetic (coil) with this permanent magnet. Ideal for commissioning and testing solenoid valves where no electrical supply is available. Can also be used as a solenoid valve manual override system. Cheap, effective and reusable in many applications.
Solenoid Valve Operating Magnet SVOM are manufactured with bore sizes 10mm (WHITE), 15 (ORANGE) or 18mm (RED) are pocket sized solenoid valve commissioning / operating permanent magnet for manual operation, checking testing or manual override for most solenoid operated valves. This magnet replaces the solenoid valve coil and operates the solenoid valve without electrical power. Can be used as a solenoid manual override converting the valve to a manual operation when placed on a solenoid valve stem (with solenoid coil removed) causing the solenoid valve to move into the energised position. A must-have for any maintenance engineer.
Each unit is manufactured and supplied with its own protective container to keep in clean and prevent collection of other metallic parts such as rust, screws, nails, pins and other random metal objects found in engineers tool box's and working environments.
Solenoid magnets can be manufactured from different ABS plastic custom colours (requires minimum quantity and additional costs) or supplied in standard colours but with custom labels and designs and logos for a smaller minimum quantity and reduced additional costs.
Magnetic strength 1500 Gauss flux density in total.
The unit consists of 3 separate magnets with 1200 Gauss each encapsulated in a strong ABS corrosion resistant case.
Magnetic stability is high the demagnetisation effect caused by exposure to external magnetic fields is low.
Maximum working temperature +250C.
Make sure you order a magnet either the same bore size or bigger than the solenoid coil it replaces. Keep away from heart pacemakers and magnetically stored data (computer discs, credit cards, audio and visual computer tapes) as stored data can be corrupted even by relatively weak magnetic fields and some equipment damaged by stronger fields. Ensure electrical power is switched off before removing solenoid coil, place magnet over valve stem, you will hear a click which is the solenoid valve moving into the energised position.
Suitable for Refrigeration, Water, Oil, Air-conditioning, gas, Air installations and other plant and machinery where solenoid valves require opening and closing manually. The Solenoid Valve Operating Magnet has been designed and manufactured to solve the problem of how to operate Solenoid Valves when a system is not under power. The Magnet is the same shape and size as a large cotton reel and, when placed on top of a Solenoid Valve with the coil removed, it causes the armature to open or close.
This means that the device can be used to operate valves in a plant or system that has yet to be wired up. It eliminates the need to wire up the system or worry about the correct voltages.
It can also be used when recovering refrigerant from a plant that has already been decommissioned and power removed. In emergencies, such as the failure of a Solenoid Valve coil, it can also be used to keep a system operating while a replacement coil is found.
HOW TO USE THE SOLENOID VALVE OPERATING MAGNET
1. Simply remove the electrically operated coil, making sure that the power is switched off.
2. Place the solenoid magnet (widest diameter at the bottom) fully over the valve stem.
3. A click should be heard, this means the valve is in the open position.
4. If no click is heard, simply turn the magnet the other way up and repeat as above.
5. When the manual operation is complete, simply replace the electrically operated coil for normal operation.
