lift Check Valve Introduction

Lift check valve (also known as lift non-return valve) is a common type of check valve, which usually consists of a valve body, bonnet, piston, spring, seals, etc. The main feature of the valve is that when the flow is forward, the piston is lifted to open the valve, and the fluid can pass through; while when the flow is reverse, the piston is resisted and compressed by the spring.

Lift Check Valve Advantages

1. Simple and reliable structure: The lift check valve has a simple and reliable structure which makes it easy to install and maintain. Its design consists of fewer moving parts, reducing the chances of mechanical failure.

2. Low fluid resistance: The lift check valve has low fluid resistance, which means that it does not hinder the flow of fluid in the pipeline, allowing for efficient and smooth operation.

3. Excellent sealing performance: The lift check valve has excellent sealing performance, which ensures that there is no backflow, preventing the loss of fluid and maintaining the integrity of the pipeline.

4. Suitable for a wide range of media: The lift check valve is suitable for a wide range of media, including liquids, gases, and steam. This makes it a versatile valve that can be used in a variety of industries.

5. Fast response: The lift check valve has a fast response time, which means that it opens and closes quickly, allowing for efficient operation of the pipeline.

6. High-temperature and high-pressure resistance: The lift check valve can withstand high temperatures and pressures, making it suitable for use in demanding applications.

Lift Check Valve Field of application

Lift check valves are usually suitable for small and medium pipeline systems, especially in the following fields:

Industrial fluid control: lift check valves can be used to control the flow of industrial fluids, such as chemical, petroleum, natural gas, water treatment and other industries.

Water supply system: Lift check valves are usually used in urban water supply systems, building water supply and drainage systems, etc., to prevent sewage backflow or water hammer.

Firefighting system: Lift check valve can be used in firefighting system to prevent backflow when the firefighting water pump stops working.

Sewage treatment: Lift check valves can be used in sewage treatment systems to prevent waste water from flowing back into clean water pipes.

Hydraulic system: Lift check valves are often used in hydraulic systems to prevent pressure leakage or damage to hydraulic components.
