Cast Iron Sluice Gates

• Gate frames, slides, and thimbles are cast from high-grade Cast Iron, conforming to:

• IS 210 FG 200 / FG 260 – Indian Standard for grey cast iron

• ASTM A126 Class B / ASTM A48 Class 30/35 – Equivalent international grades

• Small gates are cast as single-piece units, while medium and large gates are constructed from well-engineered bolted sections, offering design flexibility, ease of casting, and simplified logistics

• All gates are dispatched in fully assembled condition, factory-aligned and sealed to ensure consistent performance and reduce installation time

• Structural members are designed with appropriate safety margins to withstand hydrostatic pressures without compromising rigidity or sealing performance

• Gate components are engineered to minimise deflection under pressure, ensuring sealing surfaces remain properly aligned and leak-tight in service

• Seating faces are machined and fitted with bronze or stainless steel liners, providing durable and low-maintenance sealing

• Slides are reinforced with integral ribbing and variable wall thickness, optimised for pressure rating and gate span

• Wedge systems provide uniform sealing contact—side wedges are standard, with additional top and bottom wedges for unseating head applications

• Slide guides prevent lateral movement and ensure full support in the open position

• Thrust nut pockets are reinforced and drained to maintain structural integrity and smooth actuation

• All sealing and load-bearing surfaces are precision-machined for consistent performance, ease of operation, and extended service life.

Pressure Rating

• Fundametal’s Cast Iron Sluice Gates are structurally designed to handle a wide range of hydrostatic conditions, from low head to demanding pressure applications. Each gate is engineered based on site-specific head conditions, with appropriate ribbing, sealing strength, and spindle load capacity.

• Pressure-specific designs are offered to suit gravity flow channels, sump intakes, and pressurized zones

• Wall thickness, reinforcement ribs, and sealing interfaces are scaled and optimized to handle the intended load without deformation

• Every gate design is verified for structural stability and long-term sealing performance under submerged or fluctuating head

Opening Configurations

Fundametal Cast Iron Sluice Gates are available in three standard configurations, selected based on site layout, access limitations, and operational needs:

• Rising Spindle Type

  • The spindle moves vertically with the gate

  • Simple, rugged, and offers direct visual indication of gate position

  • Ideal for open-channel structures and above-ground installations

• Non-Rising Spindle Type

  • The spindle remains fixed while the thrust nut moves along it

  • Suitable for confined or underground spaces where vertical clearance is restricted

  • Provided with sealed housings and stem guides as needed

• Weir Type Gate

  • Allows water to overflow across the gate crest

  • Used in flow modulation, stormwater diversion, and level regulation

  • Can be operated manually or automated for overflow control

All gate types are compatible with multiple mounting and actuation systems, and can be customized based on application and site conditions.
