WCB Class 150 Flanged End Check Valve, DN100, API Standard

Such valves can be assembled in horizontal and vertical lines. The sealing surface of the disc and seat is made of alloy steel or hard alloy. With high temperature resistance, corrosion resistance, wear resistance, long service life characteristics.

Cast Steel CF8M 8” 150LB Lug End Dual Plate Check Valve

The double plate check valve has a two spring loaded plate design to open to release medium and bounce back to prevent external leakage. This effective check valve can be installed from any location, providing a tight seal and guaranteed no pressure loss.

Forged Steel A105N 1” 800LB Butt Weld Check Valve

Strong structure: forged steel check valve adopts forging process, the structure is firm, can withstand large pressure impact and vibration, has a long service life.

Forged Steel A105N 1” 150LB RF FLANGE Check Valve

High reliability: forged steel check valve has rapid, flexible opening and closing characteristics, can quickly close off under reverse pressure, and prevent the reverse flow of fluid.

Cast Steel WCB 6” 1500LB RF Flange Swing Check Valve

Flexible opening and closing: the rotary check valve is opened and closed by rotating the valve disc, with flexible operation, quick response, and no water shock phenomenon.

Swing Check Valves

Good negative pressure sealing performance: the valve disc adopts the spiral structure, rotating movement, can maintain a good sealing performance in the negative pressure environment, to avoid reflux.

MOST QUALITY CHECK VALVES FOR YOU

The check valve is basically a one-way valve and is also called a non-return valve, it is generally used in pipelines to prevent backflow.
The flow can run freely in one way and in another way the check valve will be closed to protect the piping system from the water hammer. But at the same time, it will also cause pressure loss so in piping design the risk of the water hammer and pressure loss shall be evaluated to select the right valve type.

Check Valve Parts

Sealing Element

The sealing element is vital for valves, preventing media leakage when closed. Made of durable, corrosion-resistant materials, it withstands pressure, temperature, and corrosion. Its repeated friction during operation makes material choice and manufacturing quality crucial for sealing performance and valve lifespan, regardless of valve type.

Valve Stem

The valve stem links the closure element to the operating mechanism, controlling its movement to regulate media flow. It requires strength and rigidity to withstand forces while maintaining stability. Its design and quality directly impact the valve’s flexibility and durability.

Valve Body

The valve body serves as the core structure of the valve, forming the main framework that provides installation and support for other components. It houses the internal channels for media flow. Whether it’s a ball valve, butterfly valve, or gate valve, the valve body is the most essential part, directly influencing the valve’s performance, flow characteristics, and service life.

Valve Cover

The valve cover is the enclosed part of the valve, typically connected to the valve body to form a sealed space within the valve. Its main function is to protect the internal components of the valve from external impurities and ensure complete sealing when the valve is closed, preventing media leakage. The design and manufacturing quality of the valve cover significantly impact the overall performance of the valve.
