Core selling points
- Large opening capacity: Factory-marked 2200×2200 mm class for wide culvert and canal openings.
- High structural rigidity: Deep cast ribs distribute water pressure across the leaf.
- Reliable sealing base: Machined seating faces support low leakage under design head when correctly installed.
- Hoist-ready interface: Top lug connects to screw, electric, or winch hoists.
- Project customization: Opening size, iron grade, seal type, and coating can follow drawings.
Who this product is for
EPC contractors, irrigation districts, and municipal drainage buyers who need a large cast iron penstock rather than a small canal gate. Choose this model when opening size approaches or exceeds the 2.2 m class and cast rigidity is preferred over thin steel plate.
Design and manufacturing focus
The leaf uses a thick cast body with a visible ribbed grid to resist deformation. Side rails guide vertical travel. Before shipment, sealing faces are cleaned and protected for ocean transit. Buyers should confirm civil opening tolerance, stem/hoist capacity, and whether bidirectional sealing is required.
Compatibility and accessories
- Matched screw hoist, electric hoist, or winch hoist sized to leaf weight and seating force
- Embedded frame / guide rails according to civil design
- Spare seals, stem nuts, and fasteners for maintenance stock
- Optional trash rack or coarse screen upstream of the gate
FAQ
Q1: What does 2200×2200 mm mean on this gate?
A: It is the marked clear opening class on the leaf. Confirm exact civil opening and manufacturing tolerance on the drawing before order.
Q2: Is cast iron suitable for this large size?
A: Yes within rated foundry and design limits. For much wider spans or very high heads, a welded steel gate may be more economical.
Q3: Which hoist should I use?
A: Select by leaf weight, stroke, and seating load. Many projects use electric or winch hoists at this size; small manual screws are usually insufficient.
Q4: What sealing options are available?
A: Copper alloy / bronze hard seals are common on cast iron gates. Rubber seals can be specified for certain seating designs.
Q5: Do you manufacture other sizes?
A: Yes. Non-standard openings are fabricated from drawings after technical confirmation.
Q6: What information is needed for quotation?
A: Opening size, design water head, sealing direction, quantity, destination port, and drawings if available.
Q7: How is the gate packed for export?
A: Machined faces receive temporary rust protection; crates or frames follow ISPM 15 when solid wood is used.
Q8: Can installation guidance be provided?
A: Remote installation guidance is available. On-site support can be arranged when written into the contract.
