There is a pressure relief hole at the upper end of the lift check valve bonnet. When the disc rises, the medium in the guide sleeve of the bonnet will be discharged, thereby reducing the resistance. The disc of the lift check valve does not need manual operation, and the spring components inside the valve can make it work automatically.

What Are The Advantages Of Lift Check Valves?

Lift type check valves offer several advantages in various applications due to their specific design and operation. Here are some of the key advantages of lift check valves:

Low Pressure Drop: Lift check valves typically have a streamlined design that allows for smooth flow through the valve. This results in lower pressure drop across the valve compared to some other types of check valves, making them suitable for applications where minimizing pressure loss is important.

Tight Sealing: Lift check valves provide a secure and reliable seal when closed. The vertical motion of the disc ensures that it seats firmly on the valve seat, effectively preventing backflow and leakage.

Vertical Installation: Lift check valves can be installed in both horizontal and vertical pipelines without compromising their performance. However, their vertical installation is particularly advantageous as it helps ensure consistent and predictable disc lifting.

Non-Slamming Closure: The guided vertical motion of the disc in lift control valves reduces the likelihood of valve slamming during closure, especially in applications with sudden changes in flow direction or pressure.

Wide Range of Applications: Lift check valves can be used in a variety of applications, including systems that handle liquids, gases, and steam. Their versatile design makes them suitable for industries such as water treatment, petrochemicals, oil and gas, power generation, and more.

Minimal Maintenance: Lift check valves are relatively simple in design, with fewer moving parts compared to some other valve types. This simplicity often leads to reduced maintenance requirements and costs.

Efficient Backflow Prevention: Lift check valves are effective at preventing backflow, which can help maintain the integrity of pipelines, prevent contamination, and ensure the smooth operation of systems.

Reliable Closure: The weight of the disc itself aids in its closure, making it less susceptible to fluctuations in flow conditions. This reliability is particularly beneficial in systems where consistent closure is critical.

Durable Construction: Lift check valves are often constructed from robust materials that can withstand various temperatures, pressures, and corrosive fluids. This durability ensures a long service life even in demanding environments.

Ease of Installation: Lift check valves are relatively easy to install and can be integrated into existing pipelines without major modifications.
