During the first years of activity, IMSHYDRO has already worked for important companies in the field of hydro-generation. Of all the projects, the most important references are:
· C.H. Tsanga B: Design and manufacturing of a welded body butterfly valve (DN1000 PN16) with a single acting actuator opening by oil pressure and closing by counterweight.
Includes a device which locks the valve in the fully open and in the fully closed position.
Is included a completed by-pass line (DN100 PN16) with an automatic needle valve and a manual valve.
· C.H. Freser: Design, manufacturing, supply and factory tests of a spherical valve (DN489 PN53,13) operated by a simple effect servo which opens by oil and closes by counterweight. Forged fabrication body with two covers and two bronze-aluminum mobile closing rings, which closes against two rings assembled at the ball. The downstream locking ring has a detection device for applied / unapplied positions, with double mechanical security to avoid seat application with the opened valve and valve opening with applied seat.
Includes pressurized water injection group for the valve’s seals, which takes the water from the penstock.
Includes a by-pass line (DN50 PN53,13) with an automatic double effect needle valve and a manual gate valve.
· Presa de la Almendra (IBERDROLA GENERACIÓN): Válvula de compuerta Bureau DN-1800 PN-25 para conducto de regulación de caudal ecológico. Adicionalmente, el proyecto también incluye diversa valvulería incluyendo cómo elementos más destacables una válvula de chorro hueco DN500 PN25 y una válvula de aguja DN150 PN25.
