Application scenarios：
Cast iron gates with bronze inlay are mainly used in water supply and drainage projects such as irrigation, flood control, water conservancy and hydropower, sewage treatment plants, and waterworks to cut off or regulate water flow.
Structure&Principle：
The gate adopts a rising stem (outside screw & yoke) design with a flat, reinforced panel and is installed in a wall-mounted (flush) manner. It is suitable for installation as a square orifice gate in walls where the stem rises vertically. Its flat inner bottom fits tightly against the well wall.
Operation is achieved by the hoist driving the lifting nut to rotate. Under the action of the trapezoidal thread, the screw rod drives the gate body to move up and down, thereby achieving the function of cutting off or regulating the water flow.
Main Features：
1. High structural strength, good corrosion resistance, and large pressure-bearing capacity.
2. The sealing surface is precisely machined from copper alloy, ensuring excellent sealing performance and minimal water leakage.
3. Easy installation, commissioning, maintenance, and operation.
