UNOX Stainless Steel Disc Check Valve

Stainless Steel Disc Check Valve

The UNOX Stainless Steel Disc Check Valve is engineered for reliable backflow prevention in high-temperature and high-pressure applications. Constructed entirely from AISI 316 stainless steel—including the body, disc, spring, and spring segment—this valve delivers exceptional corrosion resistance, mechanical durability, and long service life even under aggressive operating conditions.

With a wide working temperature range of –10°C to 300°C (14°F to 572°F), it is ideal for steam, hot water, condensate, chemicals, compressed air, and various industrial fluids. Its compact wafer-type design ensures easy installation between flanges while maintaining minimal pressure loss and smooth flow characteristics.

This stainless steel disc check valve offers excellent sealing performance, prevents reverse flow, and protects pumps, pipelines, heat exchangers, and other sensitive equipment in critical industrial systems.
