ASME B16.34 Axial Flow Check Valve, A216 WCB, 12 Inch, CL600

The ASME B16.34 Axial Flow Check Valve is designed to API 6D standards, featuring a carbon steel body made from ASTM A216 WCB material, ensuring robustness and durability. With a 12-inch (DN300) diameter and a pressure rating of 600 LB, equivalent to PN100, it is built for high-pressure applications. The valve is equipped with RF (Raised Face) flanged ends for secure and leak-free connections, making it suitable for critical industrial systems.

Product Name: ASTM A216 WCB Axial Flow Check Valve
Design Standard: API 6D, ASME B16.34
Body Material: ASTM A216 WCB
Size: 12 Inch, DN300
Pressure: Class 600 LB, PN100
End Connection: RF Flanged

The Axial Flow Check Valve combines the basic functionality of a check valve with the added benefits of reduced noise and lower impact, thanks to the inclusion of a spring mechanism. Its axial flow design minimizes fluid resistance, enhances flow capacity, and reduces the valve's overall size. These features make it an excellent choice for installation at the pump outlet in pipeline systems transporting oil, gas, water, and other fluids. It is specifically designed for non-return conditions, ensuring effective backflow prevention in various industries.

Product Features

» One-Piece Body: Compact, lightweight, and strong, making maintenance easy.
» Spring Thrust Force: Ensures the valve remains in the closed position even without the force of the medium.
» Versatile Sealing Carrier: Allows for installation in any direction, ensuring perfect disc-to-seat sealing.
» Axial Flow Structure: Reduces pressure loss, maintains stable flow, and prevents cavitation erosion. The disc returns to the sealing position through spring force and sub-pressure created by the medium, eliminating direct impact from the medium on the disc's backside.
» Low-Noise Operation: Designed for minimal noise during operation.
» Enhanced Disc and Pin Design: Prevents valve sticking, allowing the disc to move evenly and stay centered for consistent sealing, ensuring long-lasting sealing performance.
» Accurate Spring Force Design: Ensures the spring's thrust force is slightly greater than the combined force of the disc's gravity and friction, allowing the disc to return to its sealing position even under low pressure, regardless of installation orientation. This helps protect pump operations.
