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 .
Butterfly Type Check Valve
KOSEN Butterfly Type Check Valves is a double offset , triple offset butterfly type check valve. It is equipped with a buffer to slow down the closing speed to make partial medium enter the system in order to greatly eliminate the backflow slamming and the destructive pressure surge when pump stops working. It is mainly mounted at outlet side of the pump station in industrial water recycling supply system, urban water supply system, high-rise buildings and modern hotels. The model is designed to have non-vibration non-slam performance in consideration of special application environment. It has good sealing, smooth operation, long service life, energy saving advantage to make the living environment quiet and comfortable.Learn More

Cast Iron Check Valve
The valve disc of the swing check valve is disc shaped and rotating around the seat channel. Because the valve channel is streamlined, the flow resistance is smaller than the lift check valve. It is suitable for a large aperture with low flow velocity and unchangeable flow, but it is not suitable for pulsating flow, and its sealing performance is less than the lifting type. The swing check valve is divided into three types, single valve, double valve and multi half. These three forms are divided mainly according to the valve diameter. The purpose is to prevent the hydraulic shock from stopping the flow or reverse flow of the medium.Learn More
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.Learn More
Axial Flow Check Valve
The KOSEN Axial flow Check Valve is composed of valve body, valve seat, guide body, disc, bearing and spring. The internal flow path is streamlined design, the pressure loss is small, the valve opening and closing stroke is very short, the pump can be closed quickly when the pump is stopped, so as to prevent the sound of the huge water hammer and form the silent effect. The valve is mainly used in water supply, drainage, fire fighting, HVAC, petrochemical, electric and other industrial projects. It can be installed at the outlet of the pump to prevent the reverse flow of medium and the damage to the equipment by water hammer.Learn More
Ball Type Check Valve
The KOSEN Ball Type Check Valves is composed of valve body, valve plate and spring. It is suitable for the supply and drainage pipes. The valve is guided by the central axis of both ends of the import and export. The valve is flexible and can be installed horizontally or vertically. The valve disc is loaded by spring, and its quick closing can effectively reduce the water hammer pressure, seal performance is good, shut off without noise. It has the advantages of small volume, light weight, small fluid resistance, fatigue resistance and long life.Learn More
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.Learn More
Wafer Dual Plate Check Valve
The clamp lift check valve is a valve which is automatically opened and closed by the flow of the medium itself, and is used to prevent the reverse flow of the medium. It is also called a reverse check valve, a one-way valve, a countercurrent valve, and a back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Check valves can be divided into swing check valves (with center of gravity rotation) and lift check valves (along the axis). Valves of this type should be installed horizontally in pipes.Learn More
Cast Steel Lug Wafer Dual Plate Check Valve
KOSEN Cast Steel Lug Wafer Dual Plate Check Valves has retainer and retainerless type design. Dual-disc check valves have the advantage of zero leakage toward outside, cost saving. It can be installed in any line orientation, superior seal performance. Valves are designed in accordance to API 594 and have dual disc or single disc design and pin can be retainerless type.Learn More
Inner Wafer Dual Plate Check Valve
KOSEN Inner Wafer Dual Plate Check Valves are suitable for using on various kinds of pipeline from Class150 To Class2500, PN20 To PN420 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc.Learn More
Wafer Lift Check Valve
The Wafer Lift Check Valves consists of valve body, disc and spring. It is installed horizontally or vertically in the pipeline system to prevent the media from backstreaming. The valve has the advantages of short structure, small volume, light weight, quick closing of disc, small water hammer pressure, smooth flow passage, small fluid resistance, sensitive action and good sealing performance.Learn More
