KSB CS Swing Check Valve Dealers In Bawana Industrial Area

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
