Unico Mechanical Corp, a provider of engineered rotating equipment service, has been awarded a USD 28M contract by the U.S. Bureau of Reclamation to replace two 156-inch Butterfly Valves at the Blue Mesa Hydro Electric Powerplant in Colorado.
This extensive project, part of the Colorado River Storage Project, will significantly enhance the operational efficiency and reliability of the power plant, which supplies hydropower to the surrounding regions.
The project includes the complete replacement of two 156-inch (3.96m) Butterfly Valves, hydraulic systems, the complete refurbishment of two (2) 84-inch Ring Follower Gates, and associated structural modifications.
The technical work covers: Valve Replacement: The installation of custom-designed Butterfly Valves with stainless steel seats, resilient seals, and advanced hydraulic actuators to ensure long-term, maintenance-free operation; Ring Follower Gates: Rehabilitation of two 84-inch Ring Follower Gates, involving weld repairs and re-machining for key components such as the gate leaf and body; and Hydraulic Power Unit: Replacement of outdated hydraulic power units with new, high-performance systems to control valve operations efficiently.
The project is set to begin in December 2024, with an estimated completion date of September 2028. To ensure timely delivery and quality assurance, Unico Mechanical will collaborate with Adams Valves on the design and fabrication of the Butterfly Valves.
