Stainless Steel Wafer Dual Disc Check Valve AWWA C594

This wafer check valve is mainly composed of stainless steel valve body, stainless steel valve disc, elastic sealing valve seat, shaft, reset torsion spring and other components.

1. Super strong corrosion resistance, suitable for multi medium working conditions

Stainless steel (such as 304, 316, 316L) will form a dense chromium oxide protective film on its surface, which can effectively resist the corrosion of weak acids, weak bases, salt solutions, seawater, and humid environments. Compared with cast iron and cast steel materials, it can avoid problems such as rusting, corrosion, and perforation of the valve body. Especially suitable for pipeline systems transporting corrosive or saline media in chemical, seawater desalination, food and pharmaceutical industries.

2. Excellent hygiene performance, meeting the needs of clean fluids

Stainless steel material has a high surface finish, no pores, no adsorption of impurities, and is not easy to breed bacteria. It can be directly used in working conditions such as drinking water, food and beverage, pharmaceutical preparations, etc. that require strict cleanliness of the medium. It meets hygiene standards and solves the pain point of corrosion and pollution that cast iron valves are prone to.

3. High mechanical strength, anti-wear and impact resistance

The tensile strength and yield strength of stainless steel are much better than cast iron, and it can withstand long-term erosion from high-pressure and high flow media, as well as pressure impact during pipeline start-up and shutdown, reducing wear and deformation of valve discs and bodies, extending the service life of valves, and reducing maintenance costs for frequent replacement.

Standard export wooden case packaging

Widely used in pipeline systems in industries such as chemical, petroleum, pharmaceutical, food and beverage, seawater desalination, water treatment, HVAC, etc., it is particularly suitable for working conditions with strict requirements for medium cleanliness and corrosion resistance, and limited installation space medium flows back, and has good sealing performance.
