Stainless steel micro resistance slow closing silencing check valve is a valve specially designed for industrial, urban water supply and drainage pipelines, high-rise residential buildings, high-end hotels, and pressurized water pump outlets. This type of check valve combines micro resistance slow closing and noise reduction functions, which can effectively prevent the occurrence of water hammer and ensure the safe operation of the pipeline system. It is usually suitable for media such as clean water, mud water, seawater, sewage, etc., and can work normally in the temperature range of 0 to 80 ℃. Some models can even withstand high temperatures up to 200 ℃.
Structure and working principle
The design of the stainless steel structure micro resistance slow closing noise reducing check valves fully considers the requirements of the operating environment, using an inclined plate structure to achieve vibration free, noise free, and smooth operation. This design helps ensure quietness in hotel and residential environments, while also having energy-saving features. The slow closing function of the valves allow for a gradual closure when pumping stops, reducing the water hammer effect caused by rapid closure and protecting the pipeline and water pump from damage
Application scenarios
Stainless steel micro resistance slow closing soundproof check valve is suitable for various pipeline systems, including supply and drainage pipelines for clean water, source water, sewage, seawater and other media, such as HDPE drainage pipe and HDPE water supply pipe. They are usually installed at the outlet of the water pump to cut off the backflow of the medium, eliminate destructive water hammer, and protect the safe operation of the pipeline and water pump.
Matters needing attention
When selecting and installing stainless steel micro resistance slow closing soundproof check valves, it should be ensured that the valve model, size, and material meet the specific application requirements. In addition, the pipeline should be cleaned before installation, and the valves should be thoroughly inspected to ensure their integrity. The correct installation direction is crucial for the normal operation of the valve, and usually the direction indicated by the arrow should be consistent with the direction of the medium flow
