Bolivia F9010 Series Weir Penstock, 4-Sides-Sealing Type, Downward Opening
Product Description
■ 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
Downward Opening, to control the upstream water level, or downstream water level
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
The weir penstock is fixed on the wall by removable claws, to avoid problem happening in case anchor bolt drilling to metal parts in concrete

A weir penstock is a water control device used to regulate and isolate flow in channels, tanks, and treatment systems. It typically consists of a sliding or rising gate installed within a frame, allowing operators to adjust water levels or completely stop flow when needed. Commonly used in wastewater treatment plants, irrigation networks, and drainage systems, weir penstocks are designed for durability and corrosion resistance. Made from materials such as stainless steel or cast iron, they ensure reliable performance in harsh environments while providing precise flow control and easy operation
