Design Features & Benefits
-
Dual-Plate (Double Disc) Design: The two spring-loaded plates provide a streamlined flow path, resulting in a very low pressure drop compared to traditional swing check valves . The design's compact nature makes the valve significantly lighter and smaller, saving valuable installation space .
-
Quick Closure & Non-Slam Action: The spring-assisted plates close rapidly as soon as forward flow ceases, effectively preventing backflow and minimizing the water hammer effect that can damage pipelines and pumps .
-
RTJ End Connection (Ring Type Joint): The 1500LB pressure rating combined with the RTJ flange connection ensures a robust, metal-to-metal seal that is essential for high-pressure and high-integrity services . This design provides a reliable, leak-proof connection suitable for the most demanding conditions.
-
Easy Installation: Its wafer or lug-type design (depending on the specific model) allows for simple and quick installation between standard pipeline flanges, reducing downtime and labor costs .
-
Bi-Directional Installation: The valve can be installed in both horizontal and vertical pipelines, offering flexibility in system design .
-
Wide Temperature Range: Depending on the internal materials, the valve is suitable for a wide operating temperature range, from -196°C to +815°C, ensuring performance across various services .
