Cast Iron Sluice Gate

Cast Iron Sluice Gate is a robust,vertically sliding water control device,primarily constructed from high-grade cast iron,designed to shut off,regulate,or throttle flow in open channels,pipelines,and water control structures.

1.Core Construction&Materials

Body&Gate Leaf:Manufactured from HT250 gray cast iron or ductile iron(GGG-40),offering high compressive strength,rigidity,and natural corrosion resistance.

Gate Frame:A rigid,embedded structure fixed to concrete,serving as the guide track for the gate leaf and transferring hydraulic loads to the foundation.

Sealing System:

Metal Seal:Precision-machined bronze/copper alloy inlaid seats for long-lasting,zero-leakage performance.

Soft Seal:High-quality EPDM or nitrile rubber gaskets for applications with heavy silt or debris.

Surface Treatment:Protective epoxy paint or bitumen coating for enhanced durability in harsh water environments.

Operating Stem:Stainless steel or carbon steel lifting rod,connecting the gate to the actuator.

2.Key Features&Advantages

Exceptional Durability:Solid cast iron construction provides excellent wear resistance and a service life of 30+years.

Superior Sealing:Bi-directional sealing design with a self-tightening wedge mechanism,ensuring minimal leakage(as low as 0.03 L/m·s).

High Pressure Rating:Capable of withstanding water heads from 1 to 10 meters(0.1 MPa).

Corrosion Resistance:Ideal for use in fresh water,wastewater,and slightly corrosive environments(pH 5–10).

Versatile Operation:Compatible with manual,electric,or hydraulic actuators for precise control.

Low Maintenance:Simple structure with few moving parts,reducing long-term operational costs.

3.Standard Specifications

Types:Flat(PZ)and Arched(PGZ).The arched design optimizes stress distribution for higher head applications.

Sizes:Standard dimensions from DN 50(2")up to 4m x 6m(13'x 20').Custom sizes are available.

Pressure Class:Typically PN10/PN16.

Design Standard:Manufactured to AWWA C650 and CJ/T 3006.

4.Primary Applications

Water Conservancy:Rivers,reservoirs,canals,and flood control systems.

Municipal:Wastewater treatment plants,storm drains,and sewer systems.

Agriculture:Irrigation channels and ditches for water distribution.

Industrial:Power plants,mines,and chemical facilities for process water control.

5.Operating Principle

The gate leaf slides vertically within the frame guides.When closed,the wedge system forces the leaf against the frame seals,creating a tight,watertight barrier.Lifting the gate via the actuator opens the passage,allowing precise flow regulation.
