API 594 Dual Plate Wafer Check Valve
AEAÂ Dual plate check valve has retainer and retainer-less type design. It offers zero external leakage, cost efficiency, and versatile installation options. The superior sealing performance makes it ideal for various industrial applications. Designed in accordance with API 594, the valve is available in dual plate or single plate configurations with a retainer-less pin option.
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
- 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 and upward flow direction in 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 can be furnished with resilient seal materials that provide tight seals without leakage and metal seals with minimal leakage.
ADVANTAGE
- Face-to-face dimensions are about one fourth of a Swing Check Valve.
- Weight is as little as 20% of the corresponding Swing Check Valve due to compact design.
- Spring design allows more efficient closing when backflow occurs, reducing water hammer.
- Lower pressure drop than Swing Check Valves due to less friction resistance.
- More cost-effective due to lightness and compact design, easier and cheaper to install and maintain.
- Flangeless design allows installation between flanges.
- Horizontal flow installation typically uses a vertically positioned hinge pin.
- Available for both horizontal and vertical piping installations.
APPLICATION
