API 594 Dual Plate Wafer Check Valve
AEA Dual plate check valve features a retainer and retainer-less design, offering zero external leakage and cost-effective performance. It can be installed in any orientation and provides excellent sealing. The valves are designed according to API 594 standards, with options for dual or single plate configurations and retainer-less pin designs.
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

Â
Design Features
- Dual plate or single plate
- Spring loaded disc
- Resilient or metal seated
- Retainer or Retainer Less Design
- Round, Full Lug or Double Flange
- Light-weight & compact design
- Optional plug disc
SPRING SELECTION GUIDE
- Standard Spring: Suitable for line pressure of 0.298MPa through 0.89MPa without pressure loss, for vertical installation.
- Low Coil Spring: Ideal for gas with line pressure under 0.1MPa.
- High Coil Spring: Suitable for line pressure of 0.88MPa.
THE SEAT DESIGN OF DUAL PLATE CHECK VALVE
- No leak, no distortion seals. Seat design offers resilient seal materials for tight seals 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 corresponding swing check valves due to compact design.
- Spring design allows efficient closing when backflow occurs, reducing water hammer.
- Lower pressure drop than swing check valves due to less friction resistance.
- More cost-effective than swing check valves due to lightweight and compact design, easier and cheaper to install and maintain.
- Flangeless design allows installation between flanges.
- Horizontal flow installation typically has the hinge pin in vertical position.
- Available for both horizontal and vertical piping.
APPLICATION
Dual Plate Check Valves have been successfully used in:
- Oil & Gas
- Petrol-chemical
- Power Generation
- Refinery
- Onshore and Offshore
- Chemical Plant
- Nuclear
- Waste Incineration
- Water System
- LNG
- Shipbuilding
- Steel Industry
- General industry
