Please note: This is a Sole Source Notification. Specifications include, but are not limited to: Valves with electrical actuators, including installation; This expenditure is for seven pinch valves, and 5 electric valve actuators, plus their installation. These valves are used in the headworks building and are used with the grit pumping system. Grit is a difficult material to pump since it is a thick slurry of sand, seeds, and other dense particles. The pinch valves are specialty valves that allow closing without binding when used with a grit slurry. These valves must be present so that the grit pumps can be removed from service for maintenance or replacement. The anticipated functional life of the equipment is 20 years. Lead time for delivery of the equipment is 14 – 17 weeks. Valve actuators are used throughout the facility to both remotely operate valves and to provide valve position information to our SCADA system for remote monitoring of valves. We use ROTORK valve actuators at PRWRF. We use this manufacturer exclusively so that we can stock spare parts and are familiar with the maintenance requirements for this equipment without having to stock parts for multiple manufacturers’ equipment. ROTORK is exclusively represented by MISCO Water/TW Associates, in the state of New Mexico. The pricing provided by MISCO Water includes the valves, actuators, shipping, and installation. This is proprietary equipment. Other equipment will require stocking a separate set of replacement parts and training of maintenance personnel on this separate piece of equipment. Substituting an “as equal” piece of equipment would not be in the best interest of the facility or the City.
