API 6D Check Valves

API 6D check valves are high-performance non-return valves manufactured in strict accordance with the American Petroleum Institute API 6D standard, ensuring reliable backflow prevention and unidirectional flow control in critical pipeline and piping systems. These valves are widely used in the oil and gas, petrochemical, refining, power generation, and energy transmission industries, where safety, durability, and leak prevention are essential.

Designed for demanding operating conditions, API 6D check valves are available in multiple configurations, including swing check, dual plate, axial flow, and piston check designs. They feature robust construction, optimized flow paths, low pressure drop, and fast response to flow reversal, minimizing the risk of water hammer and system damage. Fire-safe design, corrosion-resistant materials, and full-bore configurations further enhance performance in high-pressure and high-temperature environments.

API 6D–compliant check valves are commonly installed in upstream, midstream, and downstream pipeline applications, such as transmission lines, compressor stations, pump outlets, and processing facilities. When the official API Monogram is applied, it is used in conjunction with the certified license number 6D-2251, confirming full compliance with API quality and testing requirements.
