ASTM B148 C95800 Dual Plate Check Valve, 10 IN, 150 LB, Lug

Our 10-inch (DN250) Dual Plate Check Valve is expertly crafted from ASTM B148 C95800 aluminum bronze, ensuring exceptional durability and corrosion resistance. Compliant with API 594 and API 6D standards, this valve is designed for reliable performance in demanding applications. Rated for Class 150 LB, it features a wafer-style body with lug and flanged ends, facilitating straightforward installation into pipeline systems. The valve’s dual plate design includes a central pin and spring-loaded plates that efficiently allow fluid to flow in one direction while preventing backflow. This spring-loaded, non-return valve is an effective solution for maintaining system integrity and preventing reverse flow in various industrial applications. Compared to traditional swing check valves, our dual plate design offers reduced weight and length, contributing to cost and space savings in your piping system.
