A new butterfly valve for the penstock of the largest
hydropower project in Costa Rica
A
NDRITZ HYDRO Mexico recently manufactured a new
butterfly valve for the penstock of Reventazón hydropower
plant in Costa Rica.
HPP Reventazón is located about 8 km
southwest of the city of Siquirres, midstream on the Reventazón River, which
rises in the Orosí Valley and flows to the
Caribbean Sea. With an installed capacity of about 300 MW, it is the largest
hydropower project in Costa Rica.
In December 2011, ANDRITZ HYDRO
was awarded the contract from Instituto
Costarricense de Electricidad (ICE) for
the supply of the electromechanical
equipment for Reventazón hydropower
plant (Hydro News 22). The order included four 74 MW Francis turbines,
four butterfly inlet valves, mechanical
auxiliaries, four generators, and automation control and protection systems,
as well as low- and medium-voltage
electrical power systems and one butterfly valve for the penstock.
ANDRITZ HYDRO Mexico manufactured
the butterfly valve in cooperation with
ANDRITZ HYDRO Italy. The detail engineering for valve manufacturing was
developed at our ANDRITZ HYDRO
location in Schio, Italy, and its basic
design in Linz, ­A ustria. With an inner
diameter of 6,000 mm and a design
pressure of 10 bar, it is the largest butterfly valve ever built by ANDRITZ
HYDRO Mexico.
helps Costa Rica to meet its future electricity demands.

TECHNICAL DATA
Recently, our customer was invited to
attend and witness the final pressure
and operational test for the component
acceptance. The test was performed
without incident and to the full satisfaction of the customer. Finally, the valve
was accepted and released for shipment. The transportation of the valve
was very difficult and challenging due to
the valve components size and weight.
The successful manufacturing of the
butterfly valve for HPP Reventazón constitutes an important reference for
ANDRITZ HYDRO Mexico and moreover
