Can your solenoids do this???

These tough little guys are just like ducks when it comes to water.  They are just as happy in water as they are on dry land.

The coil is precision wound using double insulated wire with  a 190 C temperature rating.  It is then overmolded with tough Nylon.  All exposed internal non-magnetic parts are machined from corrosion resistant 316 Stainless Steel (not the cheaper and less corrosion resistant 304 SS used by some).  Magnetic parts are made from 430F Stainless Steel.  All parts are passivated for improved corrosion resistance.  Finally, all parts are nickle plated to further ensure long life ---- even in water, and with most media types.

12 volt DC, 2 and 3 way  (3 way both NC and NO). Other voltages available.  The threaded nose piece easily screws into a manifold or single valve base, as shown above.

Does Your Solenoid Supplier Pass This Test??

Does Your Solenoid Supplier Pass This Test??

It is 11:00 a.m. Thursday and you discover that you need 20 pieces of a solenoid you regularly purchase the next morning to finish an order for your most important customer.  Can your present supplier have them in your hands Friday morning?

In most cases, Richway can!!!

We make systems type products too and we know the importance of having a supplier you can count on to do what others find impossible.

That’s why we keep parts and finished goods on hand for all our standard solenoids and many of our “specials.”

We bust ours to keep you on schedule. 

Materials Notes

Here is some information about the materials we use.

Magnet Wire:  We use 200C (392F) double insulated magnet wire.  This seems to be a rarity for most standard commercial grade solenoids, but it helps ensure that our solenoids will work in the most demanding conditions.

430F Stainless Steel is the "solenoid grade" stainless used for many industrial duty solenoids.  It offers good corrosion resistance and has the magnetic properties required for solenoids.  Chief among the magnetic properties are low residual magnetism, so it does not become a permanent magnet, and good magnetic strength in the presence of a magnetic field.  Note: There are other magnetic steels and stainless steels available, some having overall better properties, but cost and availability limit them to "super duty" applications.  It is used for all our pole pieces and plungers.

316 Stainless Steel is a non-magnetic stainless steel with very good corrosion resistance. Like 430F, it is the standard for industrial duty solenoids. It is used for our springs and the lower barrel tubing.

Nylon is used for injection molded parts.  Nylon offers good toughness and heat resistance and has good dimensional stability.  We can mold very thin bobbin walls, which are important for good magnetic efficiency.  We use a grade of Nylon which is excellent for our solenoid body overmolding.

Though not a material, passivation is an extremely important part of producing excellent quality solenoids.  We use a triple bath, ultrasonic tank process and do a mechanical pre-cleaning before passivation.
