Bolted Cover Tilt Disc Check Valve

The product is composed of valve body, guide body, axial movement valve disc and spring component. The product can effectively prevent the reflux of the medium. Ensure the safety of the pipeline. The valve body, disc and tail are designed as streamlined passageways with good fluid performance, minimizing flow resistance and pressure. Using high performance spring material HT/INCONELX-750, it has excellent corrosion resistance, antioxidant and excellent mechanical properties, and ensures the running state of the spring under the long working condition. Mute operation eliminates noise and water hammer in valve piping to ensure safety of equipment and piping. The opening and closing reaction is fast, and the high reliable preload spring enables the disc to respond quickly to the change of fluid pressure. Compact structure, convenient installation, vertical and horizontal installation. The valve is made of alloy steel overlaying welding cover, wear-resistant, corrosion resistant and long life.
