A cast iron sluice gate is a small flat plate gate typically composed of two parts: the gate leaf and the frame. Both the gate body and frame are made of cast iron, usually cast and machined as a whole.

Installation precautions for cast iron gate operators:

The cast iron gate should be positioned vertically, not tilted.

2. Water flow must enter the gate in the correct direction; the gate cannot withstand reverse pressure (except for two-way gates).

3. The bottom edge of the gate must not be less than 250mm from the pool bottom, and the distance between the gate frame and the pool wall should each be 300mm to ensure installation.

4. Cast iron gate valves in all series should not exceed the rated water pressure standards.

5. When installing the opening and closing machine and screw, pay attention to ensure that the machine, screw, and gate are all within the same vertical plane.

6. When the gate is raised to a high height, additional bearing frames should be added. When installing the shaft guide frame, be mindful that the threaded rod joint does not pass through the bearing frame when the gate is fully open.

7. For flange-mounted installations, place a rubber sealing gasket at the assembly joint, then fill the surrounding area and the track back with concrete a second time.
