F9000 Series Square Penstock, 4-Sides-Sealing Type

■  Unique Design

Compact integral frame profile, less welding happen on frame
Modular concept, penstock is suitable for square, rectangle and round passageway
Door rail from top to bottom, the door will never touch the frame, reduces the operating torque
All penstocks are standard On / Off seating, and 4-Sides-Sealing Type
When door at partial opening position, the water will only get through the opened passageway, suitable for throttling and regulating application
Anchor bolting and sponger rubber seal between penstock and wall, grouting is not necessary
The profile seal is vulcanized ( not bonded by adhesive ) into ONE-PIECE for long service life
Due to our Abrasion-Compensating-Device,  profile seal service life is about 3-5 times than our former design
NRS or RS spindle is available
The penstock is fixed on the wall by removable claws, to avoid problem happening in case anchor bolt drilling to metal parts in concrete

■  Materials

Penstock is an important hydraulic structure designed to control and transport water efficiently in various water management and industrial applications. It is widely used in hydropower stations, irrigation systems, water treatment facilities, and large-scale engineering projects where reliable water flow regulation is required. Made from high-strength materials such as steel, penstock provides excellent durability, pressure resistance, and long-term operational stability under demanding conditions. Its strong structure allows it to handle high-pressure water flow while maintaining safe and efficient performance. Modern penstock systems are manufactured with advanced technologies to improve sealing capability, corrosion resistance, and installation efficiency. They can be customized according to different project requirements, including size, pressure level, and environmental conditions. By ensuring smooth water transportation and effective flow control, penstock plays a vital role in improving energy production, water resource management, and infrastructure reliability. With the continuous development of renewable energy and water conservation projects, the demand for high-quality penstock solutions continues to increase. Its excellent performance, durability, and adaptability make it an essential component for modern hydraulic engineering and sustainable development.
