Universal Cast Steel Check Valves are designed and manufactured in full compliance with international standards including API 6D, BS 1868, and ASME B16.34. These swing check valves are engineered to minimize flow resistance and pressure drop, offering efficient performance in horizontal pipeline installations.
Featuring a bolted cover and free-swinging clapper, the valve disc is precisely machined and guided for automatic shutoff at zero pressure, ensuring tight sealing and long service life. With a compact structure and support for low-emission service, these valves are ideal for critical applications across oil, gas, petrochemical, and power sectors.

Key Features

» Prevents Backflow: Designed to automatically prevent reverse flow, the swing disc opens with forward flow and closes under back pressure.
» Straight-Through Flow: Full flow path minimizes pressure drop, ideal for systems requiring efficient throughput.
» Horizontal & Vertical Installation: Can be installed in both horizontal and vertical lines, ensuring flexibility in system design—provided the flow direction matches the body arrow.
» High Precision Disc: Accurately machined for reliable shutoff at low or zero pressure conditions.
» Durable Seat Ring: Lapped and screwed-in seat rings ensure long-term sealing and easy maintenance.
» Accessory Options:
  Bypass connections
  Locking devices
  Counterweights or dampers to reduce disc chatter
  Custom modifications to meet specific application needs
