Solenoid Valves

This is where Don Wolf & Associates, Inc. started our business over 20 years ago.  Don Wolf, Sr. had a great relationship with several solenoid valve customers when he worked as a sales manager for ITT General Controls.  That good will brought those customers to him when he decided to do this on his own.  He began a handshake relationship with Precision Dynamics Solenoid Valves (now Predyne division of Gems Sensors and Controls) back in 1983 and hasn’t looked back.  Predyne makes custom, specialty solenoid valves for a wide variety of applications at very competitive prices.

Valcor Scientific is a long-established manufacturer of some of the finest solenoid valves and pumps know to the world.  Their quality far exceeds most manufacturers in the market as is evidenced by their supplying to the aerospace market.  They have a patented “shear seal” design that has to be seen to be appreciated. Imagine a solenoid-actuated gate valve that operates in milliseconds and you’ll get the idea.

Kuhnke Automation is a pneumatics, one-stop shop for all of your automation needs.  If they don’t have it you didn’t need it in the first place.  Miniature, din rail mounted, stackable solenoid valves in 2, 3 and 4 way configurations are available with a variety of connections, voltages and pressure ratings.  Try stumping us on any pneumatic control application.  We double dog dare ya!

Kelly Pneumatics, Inc. (KPI) is a proportional solenoid valve manufacturer that’s turning a lot of heads in the industry.  They’ve taken a low mass solenoid operator and redesigned it to essentially “float” at a precise (and virtually infinitely adjustable) distance over the valve’s internal orifice.  This action will accurately and repeatably regulate flow through that orifice.  The valve’s electronic controller can get its feedback from any one or multiple sources of measurement upstream or downstream of its location.  Pressure, flow and even temperature sensors can communicate with this smart valve.

We at DW&A, with the help of Predyne and our loyal customers out there, have designed what is probably the very best solenoid valve series ever developed for use in cryogenic applications.  Bold statement?  Yep, and quite true!  Liquid nitrogen, (LN2) is a non-lubricating, harsh service for any valve, little less a high cycle-rate solenoid-operated valve.  Their most common use is in environmental chambers where the temperatures need to be held to exact tolerances.  That translates into a valve being opened and closed millions of times in only a few months.  Most other manufacturer’s valves die after only a few hundred thousand cycles but ours have been tested to last over 6 million!  Prepare to be amazed...
