Butterfly Valves

Valves for maintenance or safety purposes, they are engineered and customized to the special needs of hydroelectric power plants. Used as isolation device, they provide tight shut-off when closed and little pressure loss when open. Relatively easy to operate, they require limited room for installation. Large sizes are designed with biplane disc, lattice type and double eccentric execution. We produce single or double seat type valves.
