Due to being made of PVC, it has excellent corrosion resistance, chemical resistance, and water resistance.
In a trough-shaped waterway, the supernatant water from the sedimentation tank overflows through a V-notch. It is lightweight and can be constructed easily and quickly.
A lineup of water supply and drainage products including cast iron movable weirs, gate opening and closing devices, and flap valves!
This catalog introduces the water supply and drainage products handled by Saito Iron Works. With a rational and simple structure, the wedge is designed to be adjustable, making it easy to adjust in case of repairs, such as the "cast iron sluice gate," and the "cast iron movable weir," which was developed from years of manufacturing experience for the purpose of flow measurement and water level adjustment. In addition, we also introduce products such as the "telescope valve," "gate opening and closing device," and "flap valve." Please use this for selecting products.

Consideration for the environment and excellent economic efficiency.
The SR synthetic fluctuation weir controls water levels and flow rates in general rivers, waterways, dams, and reservoirs. It is the latest construction method developed by Obermeyer, incorporating detailed technological innovations that achieve outstanding effects in terms of environmental consideration, stability, and cost-effectiveness.
![[Construction Case] Certain Housing Complex - Trench and Center Well Replacement Work](https://image.www.ipros.com/public/product/image/68e/2000495269/IPROS51993025710691471708.png?w=280&h=280)
This is a case study of the replacement work of an aging iron overflow weir with a new resin one.
We would like to introduce a case of replacing an aging iron overflow weir in a certain housing complex with a new resin one. The existing overflow weir at the site was at risk of falling due to aging, necessitating prompt restoration. After a site survey, we manufactured an overflow weir of the same size using PVC and carried out replacement work including surrounding equipment. 【Construction Case】 ■ Manufacturing Days: 14 days ■ Type of Work: Equipment Installation ■ Working Days: 2 days ■ Date/Location: June 2019/Shiga Prefecture ■ Equipment Used: Trench, Center Well *For more details, please refer to the PDF materials or feel free to contact us.
For preventing hazards and water theft! The winding speed is fast, so the setup operation time is short.
We would like to introduce the "Wire-type Tilt Weir" handled by Inoue Iron Works Co., Ltd. This product allows for safe tilting at a constant speed due to the adoption of a centrifugal brake. The winding speed is fast, which shortens the time required for the upright operation. Additionally, it is equipped with an interlock mechanism, making it safe as the weir cannot be tilted when the handle is attached. It is widely used as a water storage weir in relatively narrow irrigation channels. 【Features】 ■ High efficiency ■ Prevention of hazards ■ Prevention of water theft ■ Safe tilting at a constant speed due to the adoption of a centrifugal brake ■ The float and float guide are made of stainless steel, eliminating the risk of corrosion *For more details, please refer to the PDF materials or feel free to contact us.
Constructing a dam as needed by sealing or discharging air and water! It combines durability and safety.
The "Rubber Dam" is a rubber weir that has a simpler civil structure compared to other gates, making maintenance easy and maintenance-free. It enables low-cost, high-performance flood control and water utilization. Since the rubber is inflated with compressed air, there is no need for equipment such as hydraulic cylinders, eliminating concerns about oil leaks into the river. Nihon Jidoki Kogyo Co., Ltd. constructed its first rubber-coated fabric weir in 1964 and has continued to install this product at over 530 locations. 【Features】 ■ Can accommodate various river cross-sections and bank slopes ■ Installable in various sizes, from small sizes to long sizes near estuaries ■ Design can be tailored to river conditions and intended use *For more details, please refer to the PDF materials or feel free to contact us.
Since it is made of FRP (fiberglass reinforced plastic), it has excellent corrosion resistance, chemical resistance, and solvent resistance.
In a trough-shaped waterway, the supernatant water from the sedimentation tank overflows through a V-notch. It has a high tensile elongation rate and is resistant to impact.
Reliable technology in water resource management and flood control brought by over 900 successful projects! Economical and aesthetically pleasing.
We would like to introduce the spillway that is handled by Nippon Automatic Machinery Co., Ltd. It is designed to pivot around a hinge located at the bottom of the door body, and since there are no tall structures like roller gates, it is more economical and aesthetically pleasing than long-span roller gates. There are two types available: the torque axis type with a hydraulic cylinder inside the side wall, and the rear push-up type with the hydraulic cylinder located at the back of the gate. 【Features】 ■ Pivots around a hinge located at the bottom of the door body ■ No tall structures like roller gates ■ More economical than long-span roller gates ■ Excellent aesthetics ■ Available in two types: torque axis type and rear push-up type * For more details, please refer to the PDF materials or feel free to contact us.
