Swing Check Valves are essential non-return valves designed to prevent backflow in piping systems automatically. Utilizing a gravity-actuated swinging disc mechanism, these valves allow for a full, unobstructed flow when open and provide a rapid, tight seal when the flow reverses. Their robust construction and low-pressure drop characteristics make them an ideal choice for water treatment, oil and gas pipelines, and general industrial infrastructure. Designed for durability, our swing check valves minimize maintenance requirements while ensuring high-integrity backflow prevention in critical process loops.

Manufactured to meet stringent global standards such as BS 1868, API 6D, and ASME B16.34, these valves are available in bolted bonnet or pressure seal designs for extreme high-pressure services. We offer a wide range of body materials including WCB, CF8M, and Super Duplex, with seat options like Stellite for superior wear resistance. For systems prone to water hammer, specialized configurations with lever and weights or external dashpots are available to control the closing speed. Whether in desalination plants or petrochemical refineries, our swing check valves provide reliable, long-term performance across Saudi Arabia’s industrial hubs.



Swing Check Valves Features

  • » Automatic Backflow Prevention: Features a self-actuated swinging disc that responds instantly to flow reversal, ensuring high-integrity protection for pumps and compressors.
  • » Full-Port Unobstructed Flow: The disc swings completely out of the flow path when fully open, resulting in extremely low pressure drop and high flow efficiency.
  • » Robust Bolted Bonnet Design: Equipped with a heavy-duty bolted bonnet for easy access to internal components, simplifying maintenance and seat inspections without removing the valve from the line.
  • » Severe Service Pressure Seals: Available with pressure-seal bonnet configurations for ultra-high-pressure applications, where system pressure is utilized to tighten the seal.
  • » Stellite Hard-Faced Seating: Seats are typically hard-faced with Stellite or 13% Cr to resist erosion, wear, and corrosion, significantly extending the valve’s service life.
  • » Optional Lever and Weight: Can be customized with an external lever and weight or dashpot to assist in closing and to minimize the risk of water hammer in liquid systems.
  • » Versatile Mounting Positions: Primarily designed for horizontal lines, but can be installed in vertical lines for upward flow applications.
  • » International Quality Compliance: Fully compliant with API 6D, BS 1868, and ASME B16.34 standards, ensuring reliability in oil, gas, and power generation sectors.
