API 594 Dual Plate Wafer Check Valve
AEA Dual plate check valve is designed with both retainer and retainer-less configurations. This type of valve offers excellent sealing performance with zero external leakage, making it a cost-effective solution. It can be installed in any orientation, providing superior sealing and reliability. The design complies with API 594 standards and features either dual or single plate options with optional retainer-type pins.
Â
Product Range
- Valve size: 2" ~ 40" (DN50-DN1000)
- Pressure: ANSI Class 150~2500 (PN16-PN420)
- Temperature: -196ºC ~ 500ºC
- Body Materials: Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel
- Trim (Disc/Stem): Carbon Steel, Stainless Steel, Duplex Steel, Alloy Steel
Â
Technical Specifications
- Design: ASME 16.34/API 594/API 6D
- Face to Face: ASME B16.10
- End Flange: ASME B16.5, ASME B16.47
- BW End: ASME B16.25
- Test: API 598/API 6D/BS 6755
- Special: NACE MR-01-75
Â
Design Features
- Dual plate or single plate design
- Spring loaded disc for quick closing
- Resilient or metal seated for optimal sealing
- Retainer or retainer-less design
- Round, Full Lug, or Double Flange types
- Light-weight and compact design
- Optional plug disc available
SPRING SELECTION GUIDE
- Standard spring suitable for line pressure between 0.298MPa and 0.89MPa without pressure loss and vertical flow direction.
- Low coil spring ideal for gas applications under 0.1MPa line pressure.
- High coil spring recommended for line pressure above 0.88MPa.
THE SEAT DESIGN OF DUAL PLATE CHECK VALVE
- No leak, no distortion seals. Seat design includes resilient materials for tight sealing and metal seals with minimal leakage.
ADVANTAGE
- Face-to-face dimensions are about one fourth of swing check valves.
- Weight is as little as 20% of swing check valves due to the compact design.
- Spring design ensures efficient closure during backflow, reducing water hammer effects.
- Lower pressure drop than swing check valves due to reduced friction resistance.
- More economical than swing check valves due to lightweight and compact construction, easier installation and maintenance.
- Flangeless design allows installation between flanges.
- Horizontal installation typically requires the hinge pin to be in a vertical position.
- Installation is possible in both horizontal and vertical piping systems.
APPLICATION

- Oil & Gas
- Petrochemical
- Power Generation
- Refinery
- Onshore and Offshore
- Chemical Plant
- Nuclear
