Check valves are essential components in high-pressure pipelines, expertly engineered to control fluid flow in a single direction while preventing any backflow to the pump. This critical function ensures the utmost safety and integrity of your pipeline systems.
The API 6A Check Valve features an innovative design where the opening and closing components intuitively respond to the flow of the medium. This makes it ideal for use with clean mediums, although it is not recommended for mediums containing solid particles or those with higher viscosity.
Design Features:
With a well-thought-out structure, reliable sealing, and an aesthetically pleasing design, this valve is a standout in both function and form.
The valve disc ensures rapid closure and features highly flexible action, contributing to seamless operation.
Enjoy the advantage of low maintenance costs which contribute to overall operational efficiency.
Benefit from minimal maintenance requirements, with no necessity for frequent lubrication and upkeep in the short term.
Our check valves are available in three sophisticated types: top-entry, dart, and flapper. The top-entry and flapper variants boast fully encased flappers that significantly prolong abrasion life, making them ideal for fluid services. In contrast, dart check valves are equipped with robust dual seals of stainless steel and seal rings, tailored for optimal performance in gas services.
