The 316 Stainless Steel Dual Plate Wafer Check Valve is a high-performance, space-saving solution engineered for dependable non-return operation in industrial and process systems. Designed to meet API 594 standards, this valve features a dual spring-loaded plate design that ensures quick closure, minimising water hammer and protecting pumps and pipelines from reverse flow.
Manufactured from ASTM A351 CF8M (316 stainless steel), the valve offers outstanding corrosion resistance and long service life in water, chemical, and marine environments. Its wafer-type body fits easily between flanges to ANSI B16.5 Class 150 dimensions, making it ideal for both new installations and retrofits where space and weight are critical.
A dual plate wafer check valve is used to prevent reverse flow in piping systems while maintaining a compact, lightweight profile suitable for tight installation spaces.
The dual plate, spring-loaded design allows for fast closing response, helping reduce water hammer, vibration, and potential damage to pumps and pipelines.
316 stainless steel provides excellent corrosion resistance and durability, making it well suited for water, chemical, marine, and industrial process applications.
ANSI Class 150 compatibility indicates the valve is designed to fit between ANSI B16.5 Class 150 flanges and operate within the associated pressure and temperature limits.
Seat options typically include metal seats for higher temperature and durability requirements, or Viton seats for improved sealing performance in specific fluid applications.
