Our decision to upgrade our rotary valve on the North Cinder Hopper for No. 8 Boiler was one of our better decisions. The PMV-14 Severe Duty Rotary Valve has been operating flawlessly since installation. We have not had any issues with the valve since installation in December 2008. The installation was also without issue. The transitions that were provided by Precision were perfect. The face-to-face dimensions were right on. This was a bolt up installation/upgrade. The only modification was the installation of a heavier breaker and modification of the flex conduit and wiring in the field to accommodate the three horsepower motor over the fractional horsepower motor on me old rotary valve.

Our mechanics were particularly impressed with the modular construction and apparent ease of rebuilding the unit when me time comes. The Nord drive unit is an excellent choice and built to withstand such a harsh environment.

This is the kind of upgrade that we enjoy and will heartily recommend. One mat saves us dollars in rebuild costs, has few if any required field modifications, and provides trouble free operation. The PMV-14 was that kind of upgrade. I will certainly recommend this rotary valve to all of my peers if the subject of rotary valves ever comes up in conversation.
