Penstocks (sluice gates) isolate channel flow via a vertical sliding gate in square, rectangular or round openings from 150×150 mm to DN3000. Cast iron (GG25/GGG40) or stainless steel (SS304/316L) frames with EPDM/NBR/Neoprene or metal seats give bi-directional zero-leakage sealing under head pressure. Wall-mounted, low-friction guide rails, manual handwheel, electric, pneumatic or hydraulic actuation. For water, wastewater, flood control, irrigation, power cooling inlets per AWWA/DIN/BS.
Penstock or Pipeline Valve
A penstock, also called a sluice gate, controls water through an open channel or a concrete wall opening. A gate or
butterfly valve controls flow inside a closed pressurized pipeline. Penstocks bolt to a wall-mounted frame and seal against water head, so they are not interchangeable with ordinary pipeline valves.
Shape, Material and Actuation
Square, rectangular and round apertures are available to match the civil structure. Cast iron is suitable for general water and drainage works, while SS304 or SS316L is selected for corrosive wastewater, saline environments and chemical exposure. EPDM is the common choice for municipal water service; alternative elastomers or metal seating can be selected for specific media and temperatures.
Manual handwheels suit infrequent attended operation. Electric actuators support remote control and position feedback, while pneumatic or hydraulic cylinders suit frequent or fast operation. Frame height, stem extension, wall dimensions and maximum water head must be confirmed before production.
