Check valves are essential components in high-pressure pipelines, expertly designed to ensure unidirectional fluid flow. They prevent backflow to the pump, thereby safeguarding the integrity and safety of the pipeline system.
The 'API 6A Check Valve' operates with self-activating opening and closing mechanisms, responding intelligently to the medium's flow. This design is perfect for clean media, though not recommended for those containing solid particles or with high viscosity.
Design Features:
Ingeniously engineered with a rational structure, these valves offer reliable sealing and an aesthetically pleasing appearance.
The valve disc boasts rapid closure and exhibits flexible response actions.
Maintenance costs remain minimal.
These valves require no short-term frequent lubrication or maintenance.
Our check valves are available in three robust types: top-entry, dart, and flapper. The top-entry and flapper models feature fully enclosed flappers for prolonged wear resistance, ideal for fluid service. Dart check valves, equipped with dual seals of stainless steel and seal rings, are tailored for gas services, offering superior durability and performance.
