Sluice Gate Valve / Gate Valve
Our Sluice Gate Valves offer full bore, low pressure drop isolation of fluids. These valves are built for rugged environments, utilizing resilient or metal seating to ensure long-term durability and zero leakage under water distribution grid pressures.
Introduction
Our gate/sluice, or scour valves offer exceptional performance for various applications. Constructed from Cast Iron, S.G. Iron, Cast Steel, or Mild Steel fabricated, they feature an outside screw and yoke type with or without rising stem for reliable operation.
Key Features
- Resilient seated gate (EPDM bonded) or metal-to-metal seating.
- Low torque operation with high endurance bronze stem nuts.
- Smooth, unobstructed full-bore passage preventing debris accumulation.
- Inside screw non-rising stem (NRS) or outside screw & yoke (OS&Y) configurations.
- Corrosion resistant epoxy powder coating inside and out.

Application & Usage of Sluice Gate Valve / Gate Valve
Water Distribution System
Ideal for on/off control and isolation in municipal water supply networks, allowing pipeline segments to be isolated for repairs.
Sewage and Silt Evacuation
Used as channel gates and scour discharge valves in wastewater treatment systems and open channels to clean accumulated sediment.
Dams and Power Stations
Provides reliable isolation and scour clearance in high head conditions, protecting turbines and main pipelines.
Types of Sluice Valves based on Operation
Manual Handwheel
Equipped with traditional handwheels or cap tops for simple manual operation in standard pipeline networks.
Gearbox Operated
Equipped with bevel or spur gearboxes to reduce operating torque in high-pressure or large diameter pipelines.
Electric Actuated
Equipped with electric actuators for automated, remote control in industrial grids and purification processes.
Valve Types Based on Function
Gate Valve
Ideal for on/off control and isolation in main distribution lines with minimum pressure drop.
Sluice Gate
Slide-type gates used for flow control and sediment removal in open channels, channels, or wastewater stages.
Scour Valve
Designed for pipeline maintenance and cleaning, allowing evacuation of silt and debris from low points.
Certificates & Inspection
All valves are subjected to rigorous hydrostatic shell and seat pressure testing in accordance with standard codes (e.g., API 598 / IS 14846) prior to delivery.
- Physical dimension and wall-thickness checks
- Hydrostatic seat and shell test validation
- Manufacturer Test Certificate (MTC) and third-party inspection (SGS, TUV, RINA, IRS etc.) available
- Epoxy powder coating inspection (DFT test)
