CSK Series Subsea Swing Check Valve – Premium Quality from a Leading Velan Valve Supplier

Features & Benefits

As a trusted Velan Valve Distributor and Stockist, we proudly offer the CSK Series Subsea Swing Check Valve—engineered for extreme conditions in water depths up to 500 meters (1700 ft) with a 25+ year service life. Available in forged or cast materials, this valve ensures total reliability for high-pressure, high-temperature subsea applications.

Superior Design for Unmatched Performance

  • Piggable Swing Check Valve: Ideal for riser pipelines and subsea installations, enabling easy maintenance with pigging operations.

  • Bidirectional Sealing: The swinging disc allows forward flow and automatically closes to prevent backflow when flow stops.

  • Top-Entry Construction: Internal parts can be inspected and repaired in-line without valve removal—perfect for restricted spaces.

  • Flexible Installation: Works in horizontal or vertical (flow-up) positions, reducing downtime and maintenance costs.

Robust Material & Customization

  • Fully Customizable Materials: Tailored to meet project specs, including corrosion-resistant alloys.

  • Metal-Seated with Hardfacing: Welded-in seat ring with CoCr or Stellite overlay for extended durability.
