It is used to adjust or stop a liquid flow inside a channel or in the opening of a wall.
Penstock is composed by a frame fixed to the civil work, on which slides a shield. Sliding is made by guides in polyethylene or wheels in brass. Shield is connected to the handling system by the threaded rod. Rotating the handwheel located on top part of penstock, shield rises or lowers, varying in this way the opening or closing of channel. In position of total closing, hydraulic sealing is guaranteed by a drawn elastomer in EPDM. Basing needs, COSME penstocks can be of following types: with sealing in 3 sides, weir type, with sealing in 4 sides.
