KSB CS (Carbon Steel) Swing Check Valve is a heavy-duty non-return valve designed to prevent backflow in pipelines. It uses a hinged swing disc that automatically opens with forward flow and closes when flow reverses, protecting equipment like pumps, compressors, and boilers.
🔧 Key Features
- Carbon Steel Body (WCB / Cast Steel / Forged Steel) – high strength for demanding applications
- Swing Type Disc Mechanism – automatic operation without manual control
- Non-Return Function – prevents reverse flow and protects system components
- Low Pressure Drop – full bore design ensures smooth flow
- Hard-Faced Seat & Disc (Stellite / Alloy Steel) – long service life and wear resistance
- Bolted Bonnet / Pressure Seal Design – easy maintenance and high-pressure suitability
- Optional counterweight / dashpot to reduce water hammer
📏 Specifications
- Size Range: approx. 50 mm to 600 mm (2” to 24”)
- Pressure Class: Class 150 / 300 / 600 / up to 2500
- Temperature Range: up to approx. 593°C
- End Connections: Flanged / Butt Weld / Socket Weld
- Standards: API 6D, BS 1868, ASME B16.34
- Testing: API 598
⚙️ Construction Materials
- Body: Carbon Steel (WCB / A216), Alloy Steel
- Disc: Carbon Steel / Stainless Steel / Stellited trim
- Seat: Metal seated (hard-faced)
- Hinge Pin: Stainless Steel / Alloy Steel

⚙️ Working Principle
- Forward flow → disc swings open
- Flow stops/reverses → disc closes automatically
- Prevents backflow, water hammer, and equipment damage
⚙️ Applications
- Power plants (boiler feed & steam lines)
- Oil & gas pipelines
- Petrochemical and refinery plants
- Chemical industries
- Water & wastewater systems
- Industrial process pipelines
✅ Advantages
- Automatic operation (no external power required)
- Reliable backflow prevention
- Suitable for high pressure & high temperature services
- Low maintenance and long service life
- Protects critical equipment and systems
⭐ Conclusion
KSB CS Swing Check Valves are widely trusted for their robust construction, dependable sealing, and efficient backflow protection, making them essential for high-pressure industrial and process applications.
