Wastewater treatment sluice gate PVR

The sluice gate with manual gearbox series are used as cut off elements for channels, underwater holes, level control. They consist of an enbloc steel shield suitably stiffened, lateral seals in SBR elastomer hollow round bar, frames in standard steel sections, driving system with steel screw hinged to the gate, handwheel and gear box. Thanks to the use of a manual gearbox for the driving operations, this type of gate can be used also in the presence of a high hydrostatic thrust and for big sizes. It is a valid alternative to the PV type. The sealing can be achieved in one only direction, that is implemented on smooth wall or in both directions according to a wedge and roller scheme consisting of four sliding bronze wheels fitted shafts and four wedges bolted on the frame, so as to obtain a horizontal thrust by compressing the sealing surfaces. The sluice gates can be supplied with the seals on three sides (PV3R) or on four sides (PV4R).
