Kirloskar Cast iron Sluice Valve
Kirloskar Cast Iron Sluice Valve: Industrial Gate Valve Specifications & Uses
Kirloskar Cast Iron Sluice Valves (also known as Cast Iron Gate Valves) are heavy-duty linear isolation valves designed for full-flow fluid control in water supply networks, industrial processing plants, and wastewater systems. Manufactured in compliance with IS 14846 and BS 5163 standards, these isolation valves feature low pressure drop, drop-tight sealing, and long-term corrosion resistance.

Key Technical Features & Benefits
- Minimal Pressure Drop: Full-bore design allows straight-through fluid movement, significantly lowering friction head loss during full-open operation.
- Dual Stem Configurations:
- Non-Rising Stem (NRS): Internal stem threading makes it suitable for underground pipelines, cramped valve pits, and space-constrained applications.
- Outside Screw & Yoke (OS&Y / Rising Stem): External threads protect against media corrosion and provide an instant visual indication of valve open/close status.
- Positive Leak-Proof Sealing: Precision-machined bronze/gunmetal seating rings ensure positive shut-off under fluctuating line backpressure.
- Bi-Directional Operation: Operates effectively in either flow direction, streamlining installation in dual-flow distribution lines.
- Flexible Actuation: Can be configured with manual handwheels, enclosed spur/worm gearboxes, or electric/pneumatic actuators for automated system control.
Operating Limits & Fluid Compatibility
- Compatible Media: Clear potable water, raw intake water, municipal sewage, industrial effluents, and neutral non-corrosive fluids.
- Turbidity & Solids: Suitable for fluids carrying up to 5000 PPM suspended solids.
- Operating Temperature: Safe operation across -10°C to +70°C .
- Test Pressures: Hydrostatic body/shell testing at 1.5× rated working pressure; seat leakage testing at 1.1× rated pressure.
Primary Industrial Applications
- Municipal Water Infrastructure: Main line isolation in raw water pumping stations, elevated storage reservoirs (ESR), and municipal distribution grids.
- Wastewater & Sewage Treatment: Effluent isolation in Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP), and drainage mains.
- Power & Heavy Industry: Cooling tower water circuits, fire protection ring mains, and auxiliary industrial water supply systems.
- Agriculture & Irrigation: Lift irrigation schemes, canal headworks, and agricultural pipe networks.
- Technical & Application Search Terms: non rising stem cast iron sluice valve, OS&Y rising stem gate valve IS 14846, large diameter sluice valve 300mm to 1200mm, FBE coated water works gate valve, flanged sluice valve for sewage treatment
