Clapet anti-retour à bride forgé API
This API forged flanged check valve is designed to prevent reverse flow and safeguard equipment in pipeline systems. The valve body is integrally forged, delivering strong structural integrity and reliable performance under varying operating conditions. Flanged ends allow secure connection and convenient maintenance. The valve functions automatically based on flow direction, ensuring consistent non-return performance in oil, chemical, and energy-related applications.

Caractéristiques structurelles de
The body is crafted from premium Acier forgé ASTM A105N, eliminating internal porosity through high-pressure forging. When handling permeable media like crude and refined oils, it ensures superior shell density, providing a more reliable leak-proof barrier than castings, especially in high-safety zones like oil transfer stations.
Utilisant de l'acier inoxydable ASME B16.5 standardized flange ends, the installation process is greatly simplified. In chemical process skids ou les municipal utility networks, the flanged design allows technicians to quickly remove and replace valves for routine inspection without cutting the pipe, significantly reducing maintenance downtime.
The bonnet is secured by four high-strength bolts and a spiral wound gasket. This configuration maintains stable pre-load even under pressure pulsations in industrial cooling systems ou les low-pressure steam lines, effectively preventing seal failure caused by vibrations and ensuring long-term external sealing in harsh environments.
The disc features a guided lift design, operating automatically based on fluid pressure. This precision-engineered travel path enables an extremely rapid response when handling gaseous media like air comprimé ou les gaz naturel, neutralisant efficacement l'impact du reflux et protégeant les instruments sensibles en aval.
Grâce à la stabilité chimique de l'A105N, cette vanne est largement applicable dans des scénarios tels que l'approvisionnement/drainage d'eau, les cycles thermiques, et les réseaux auxiliaires pétrochimiques. La garniture est optimisée pour les fluides non corrosifs, maintenant d'excellentes performances sur un large spectre de température allant de -29°C à 425°C.
