Cast Steel Non-slam Nozzle Check Valve
The KOSEN Non-slam nozzle check valves is a streamlined venture port design so as to reduce pressure loss. This series valve disc is the only moving part to minimize internal wear and compressed disc spring initiates valve closure as flow slows down and provides quick reaction on flow velocity change. It can be used in a wide range of critical and demanding services applications such as fast reversing reciprocating compressor system or installations where the check valve must be placed in close proximity to the pump inlet or outlet.

Forged Bronze Check Valve
KOSEN Forged Bronze Check Valves is used to prevent back flow in the line .Flow is in a straight line through the valve resulting in minimal pressure drop . The disc swings into the open position as the media flows through the line .Back pressure in the line holds the disc in the closed position .
KOSEN Forged Bronze Check Valves may be installed in horizontal or vertical lines ,but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body .
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.
