Variable Frequency Drives

Boost Efficiency, Save Money with Valley® Water Management

There’s no reason to spend more money than necessary to operate your irrigation equipment. Installing a Variable Frequency Drive (VFD) will control your pump motor’s speed to deliver only what your operation needs to function at optimal efficiency. You’ll dramatically boost energy savings by preventing over pumping and over pressurizing of your irrigation equipment. And energy savings means cost savings!

Valley® Water Management has partnered with Yaskawa™ to bring you the highest-quality, highest-performing VFD for agriculture. The Yaskawa iQPump®1000 VFD (or Valley Water Management VFD) leads the industry in performance and features for agricultural irrigation applications and is now available through your local Valley dealer.

Why choose the Valley Water Management VFD?

  • Money savings – Energy savings produce meaningful cost savings that you will continue for many years.
  • Multiple control options – Control your drive via pressure, flow, level, or any factor you prefer.
  • Highly reliable – Field proven in the ag market with thousands of units in operation.
  • Versatility – Powerful water pumping software  from Yaskawa 

Valley drives also offer numerous built-in protection features ensure your pumping solution operates smoothly and protect your investment if something does go wrong. All these protection features are standard on our VFDs. 

NEW: Valley Water Management Offering Soft Starts

Valley Water Management also is partnering with Motortronics to provide soft starts for its pump stations, as well as for general sales to Valley dealers. Motortronics is the world leader in soft start technology and manufacturing. It has decades of experience in building soft starts and private label soft starts for some of the biggest electronics companies in the world.

The soft starts are available in two standard configurations. The first is a standard run/bypass model, VIPS-S. This model has run-rated bypass contactors that close and operate the motor once it is up to speed. The second standard configuration is a start/bypass model, VIPS-H. This model has bypass contactors that are rated for the full starting current of the motor and allow the motor to be started across the line if anything should happen to the soft start. Both come standard in a NEMA 4 enclosure.
