For temporarily blocking or permitting water flows at high pressures
Due to the very rigid design, the penstocks are easy to operate by means of a spindle for closing an opening with high water pressures. Default constructed for water pressures of 10 metres of water column (mWC) with a double sluice function.
The KSA-HD penstock is produced as double sluice function as standard. The penstock consists of a vertically movable stainless steel sliding plate that seals off a circular opening in a wedge shape. The wedged sliding plate is adjustable all around. After manufacturing its adjusted precisely by the KWT specialists according to the project requirements. The seal is obtained by means of an special EPDM rubber, placed in the sliding plate, which reverses the water pressure on both sides. Due to the pressure requirements and mounting surface intolerance, the frame of the HD penstock is hollow to allow a concrete grout seal to be placed to provide the pressure security between the penstock and wall.
