Wafer Dual Plates Check Valve Stainless Steel Material Non Return Valve for Water Oil Gas

The Xidelong Wafer Dual Plates Check Valve is a high-performance non-return valve engineered for reliable backflow prevention in demanding industrial pipeline systems. Featuring a robust stainless steel CF8M (A351 Grade 316) body and dual spring-loaded discs, this wafer-type check valve delivers exceptional corrosion resistance, rapid closure, and maintenance-free operation across a wide range of applications.

Key Features

Feature Benefit
Dual Plate Spring-Loaded Design Torsion spring mechanism ensures instant, bubble-tight closure when flow reverses, preventing water hammer and system damage
CF8M Stainless Steel Body & Discs Superior corrosion and oxidation resistance; suitable for aggressive media including seawater, chemicals, and high-temperature fluids up to 200°C
Compact Wafer Configuration Ultra-short face-to-face dimension (per API 594) saves installation space and reduces pipeline weight; fits between standard flanges without additional supports
Soft Seat Leak-tight sealing at low differential pressure; broad chemical compatibility; replaceable seat extends valve service life
Bi-Directional Sealing Positive shutoff in both flow directions; fire-safe secondary metal-to-metal seat backup available on request

Technical Specifications

  • Nominal Diameter: DN65 (2-1/2 inch)
  • Pressure Rating: PN16 (Class 150 equivalent)
  • Body & Disc Material: ASTM A351 CF8M (316 Stainless Steel)
  • Seat Material: Virgin PTFE
  • Spring Material: Stainless Steel 316 (Inconel X-750 optional)
  • Connection Standard: Wafer type, fits between EN 1092-1 PN16 / ASME B16.5 Class 150 flanges
  • Design Standard: API 594, API 598, EN 13709
  • Face-to-Face: API 594 Short Pattern
  • Working Temperature: -29°C to +200°C (-20°F to +392°F)
  • Applicable Media: Water, hot water, steam, oil, gas, weak acids, organic solvents

Typical Applications

  • Water Treatment Plants: Pump discharge backflow prevention in raw water, treated water, and sludge lines
  • HVAC Systems: Chilled water, condenser water, and hot water circulation loops
  • Oil & Gas: Refinery process lines, tank farm piping, and fuel transfer systems
  • Marine & Shipbuilding: Ballast water systems, bilge discharge lines, firefighting mains
  • Chemical Processing: Corrosive media transfer where 316 SS compatibility is required
  • Power Generation: Cooling water circuits, auxiliary piping, condensate return lines

Quality Assurance

Every Xidelong dual plate check valve undergoes the following quality control procedures before shipment:

  • 100% shell pressure test per API 598 at 1.5x rated pressure
  • 100% seat leakage test at 1.1x rated pressure with zero visible leakage
  • Material certificate (EN 10204 3.1) for body, disc, and trim components
  • Dimensional inspection against API 594 face-to-face tolerances
  • Full traceability from melt lot to finished product

For custom configurations, including NACE MR0175 sour service trim, cryogenic extensions, or special flange drilling patterns, please contact our engineering team. We offer OEM branding and tailored packaging solutions to meet your project requirements.
