Product Description

Material Selection

Check valves boast diverse material selections tailored to different working conditions. Common options include PVC, brass, and stainless steel. PVC check valves excel in corrosion resistance, making them ideal for low-pressure fluid systems like domestic water pipelines. Brass check valves offer excellent durability and conductivity, suitable for medium-pressure industrial applications. Stainless steel variants stand out in high-temperature and high-pressure environments, such as chemical processing equipment.

Structure

In terms of structure, the dual-plate check valve features a compact design with two symmetrical valve discs. This structure reduces flow resistance and ensures quick closing responses. The lift check valve adopts a vertical disc movement structure, which provides tight sealing performance, especially in pipelines with strict leakage requirements.

Usage

When it comes to usage, check valves need to be installed in the correct flow direction as indicated by the arrow on the valve body. They should be placed at the outlet of pumps or the end of pipelines to prevent backflow effectively. Regular inspection of valve discs and springs is necessary to maintain their functional reliability.
