ABS Check Valve Type 562 Rp Female Thread DN10-DN50 PN10

  Datasheet (PDF)

The Georg Fischer Type 562 ABS check valve with female parallel Rp threaded ends provides dependable non-return flow control for industrial piping installations. Designed for nominal dimensions from DN10 up to DN50 (thread sizes 3/8 inch through 2 inch), this valve operates reliably at a nominal pressure rating of PN10 (10 bar at 20 degrees Celsius). Manufactured from high-grade Acrylonitrile Butadiene Styrene (ABS), it exhibits outstanding impact resistance, mechanical durability, and chemical resistance across demanding environments such as chilled water loops, industrial cooling systems, and commercial water treatment plants. As an authorised Georg Fischer distributor, BigWeld supplies this precision valve across Europe for critical applications where backflow prevention is essential.

At the heart of the Type 562 check valve is an advanced, flow-optimized internal mechanism. The valve cone features a robust double-guided stem that ensures smooth, perfectly aligned axial movement during opening and closing cycles. Assisted by a high-tensile 1.4310 stainless steel spring, the valve delivers instantaneous, vibration-free shut-off even under turbulent conditions and high fluid velocities. The integrated high-grade EPDM seal guarantees tight shut-off with a hydrostatic sealing threshold as low as a 1-meter water column (0.1 bar). The hydraulic profile minimizes turbulence and pressure drop, maintaining optimum energy efficiency across pumping and circulation circuits. The spring mechanism ensures reliable functioning whether the valve is installed horizontally or vertically in upward flow configurations.

Engineered for efficient assembly and long-term serviceability, the Type 562 incorporates a true-union body architecture with ABS union nuts and threaded ends. It shares the standardized, compact installation length of Georg Fischer Type 546 ball valves, enabling direct drop-in replacement or straightforward retrofitting within existing plant layouts (incompatible with the legacy Type 360 series). The double union ends permit radial removal from the line without disturbing adjacent pipework, substantially accelerating maintenance, inspection, and servicing routines in busy industrial facilities.
