ABS Check Valve Type 562 PN10 d16-110 mm

  Datasheet (PDF)

The Georg Fischer ABS Type 562 check valve is an industrial spring-loaded non-return valve engineered to prevent backflow and hydraulic shock in pressurized liquid systems. Designed for metric pipe networks from d16 mm to d110 mm, this PN10 rated valve combines high impact resistance with chemical stability. BigWeld is an authorised Georg Fischer distributor, supplying these premium thermoplastic components for cooling circuits, water treatment, and demanding industrial utility installations across Europe.

Technical specifications

The Type 562 check valve utilizes an internal spring mechanism and a flow-optimized cone to ensure instant, dependable shut-off. Its double-guided closing cone minimizes turbulence and head loss while eliminating vibration during rapid cyclic operation.

The internal geometry guarantees dependable seal engagement at nominal pressures up to 10 bar at 20 degrees Celsius. High-grade EPDM elastomer seals maintain absolute leak-tightness even in idle flow conditions, preventing backpressure leakage and unwanted fluid mixing.

• Nominal pressure rating: PN10 (10 bar at 20 degrees Celsius) across all diameters.
• Body material: Acrylonitrile Butadiene Styrene (ABS) with high impact strength.
• Sealing element: High-grade EPDM gaskets for dependable chemical and fluid containment.
• Spring mechanism: Corrosion-resistant 1.4310 stainless steel for silent, rapid closing.
• Closing mechanism: Flow-optimized, double-guided return cone preventing seat jamming.

Installation and jointing

The integrated return spring allows mounting in any pipeline orientation, whether positioned vertically, horizontally, or inclined. This versatility simplifies complex equipment skid layouts where gravity-dependent flapper valves cannot operate reliably.

The valve incorporates metric solvent cement sockets for homogeneous jointing into ABS piping networks using Tangit ABS adhesive and dedicated cleaner. The face-to-face installation dimensions match the standard Georg Fischer Type 546 ball valve series, facilitating modular interchangeability and standardized piping design. Please note that this valve body is not compatible with Type 360 union components.

Applications

ABS check valves provide exceptional resistance to scaling, internal encrustation, and aggressive liquid environments where conventional metal valves suffer from corrosion. The robust ABS material retains mechanical ductility and toughness at low and medium operating temperatures.

Typical deployment areas include industrial cooling loops, secondary refrigeration and chilled water systems, industrial water treatment plants, marine installations, and potable drinking water distribution. As an authorised Georg Fischer distributor, BigWeld provides complete system compatibility across industrial piping networks.
