Product details:

DN800 Check Valve with Heavy Hammer is a large-diameter automatic check valve specially designed for high-flow, high-pressure pipeline systems. It is mainly installed at the outlet of large water pumps, large-diameter water supply and drainage pipelines, and petrochemical transfer pipelines.

Its core function is to prevent medium backflow, eliminate water hammer impact, and protect the safety of pipeline systems, pumps and related equipment from damage caused by backflow and water hammer.

The valve is equipped with a two-stage slow-closing buffer device, which can effectively reduce the impact of water hammer and avoid pipeline vibration and damage caused by sudden closing.

What are the characteristics and biggest advantages of DN800 Check Valve with Heavy Hammer?

① Low flow resistance and high flow efficiency, suitable for large-diameter high-flow scenarios
The DN800 model adopts an integral full-flow channel design, with smooth inner wall and small friction coefficient, which effectively reduces the head loss of the pipeline.

② Stable heavy hammer structure, reliable backflow prevention and water hammer elimination
The biggest advantage of this valve is its high-strength heavy hammer energy storage structure, which uses gravity to provide stable closing torque, and the hydraulic system is greatly simplified, making it more safe and reliable compared with ordinary check valves.

③ High sealing performance, strong corrosion and wear resistance, long service life
The valve disc is coated with PTFE composite material or NBR rubber, which has excellent wear resistance and sealing performance, and the service life of the valve disc can reach more than 800,000 times under normal working conditions.

④ Convenient operation and maintenance, strong interchangeability
The valve structure is simple, the wearing parts are standardized, and all equipment and related parts have absolute compatibility, which is convenient for later maintenance, replacement and disassembly, and reduces maintenance cost and downtime.

⑤ Strong adaptability, suitable for harsh working conditions
The DN800 Check Valve with Heavy Hammer has a wide operating temperature range of -29℃~425℃, which can adapt to the working conditions of high-temperature steam and low-temperature media.

Application Conditions of DN800 Check Valve with Heavy Hammer

It is widely used in water conservancy, thermal power, municipal water supply and drainage, petrochemical, metallurgical, sewage treatment and other industries.

Specific application areas include:

1. Large-scale pump stations (water supply, sewage, water conservancy).

2. Petrochemical industry: Used in large-diameter crude oil, refined oil and gas transmission pipelines, it prevents the backflow of oil and gas, avoids cross-contamination of media and pipeline explosion accidents caused by backflow.

3. Thermal power plants: Installed in the steam and water supply pipelines of thermal power plants, it prevents the backflow of high-temperature steam and water, ensures the normal operation of the boiler and steam turbine.

4. Municipal water supply and drainage projects.

5. Metallurgical industry.
