Kirloskar Cast Steel Check Valves (also known as Non-Return or Reflux Valves) are heavy-duty industrial valves built to automatically prevent fluid backflow in high-pressure and high-temperature pipelines. Manufactured by Kirloskar Brothers Limited (KBL), these valves are highly favored by National Thermal Power Corporation (NTPC), oil refineries, nuclear power setups, and water supply boards across India.
They are typically designed with a swing-type disc and bolted cover configuration to ensure rigid, slam-less uni-directional flow operation.
Core
