Válvula de retención de bola de acero inoxidable 316, rosca hembra de 1½", 16 bar, DN40, tipo M1 - 0080497

Ball Check Valve Stainless Steel 316 1½” Female Thread 16 bar DN40 Type M1

Rated to a full 16 bar working pressure and sized at DN40 (1½”), this spring-loaded ball check valve delivers a maximum flow capacity of 57.8 m³/h — making it well suited to high-demand pool plant rooms, commercial water-treatment circuits, and industrial fluid-handling systems where robust backflow prevention is required. The entire wetted flow path, including the body, housing, and spring, is manufactured from grade 316 stainless steel for long-term resistance to chlorinated water and aggressive media. With a temperature range of 0 °C to 90 °C, this valve covers both ambient pool-water and heated domestic installations without compromise.

All-316 Stainless Construction

Unlike carbon-steel or brass alternatives, every structural component — body, housing, and return spring — is grade 316 stainless steel, the alloy recognised for its superior resistance to chloride-induced corrosion. The NBR (nitrile rubber) ball and seal seat provide a reliable, drop-tight closure under backpressure while remaining compatible with water, pool chemicals, and a broad range of industrial fluids within the stated temperature envelope. This materials pairing is a standard specification for demanding pool-plant and process pipework where longevity and minimal maintenance are priorities.

Backflow Prevention & Installation

As a ball-type check valve, flow is permitted in one direction only; when forward pressure drops or reverses, the spring-loaded NBR ball seats firmly against the body, preventing backflow without manual intervention. The 1½” female BSP thread ends allow direct inline fitting to standard threaded pipework and pump outlets common in European pool and HVAC plant rooms. With a face-to-face length of 190 mm and a centre-to-top dimension of 99 mm, the valve can be planned into pipework layouts with confidence. The valve can be installed in horizontal or vertical flow-upward orientations.

Tallas y compatibilidad

At DN40, this valve is appropriate for main circulation lines serving larger residential pools (typically 80 m³ and above) or commercial pool plant rooms where pump outputs regularly exceed 20–30 m³/h. The 16 bar pressure rating also extends its usefulness beyond pools into heating, cooling, and industrial fluid circuits. Threaded female connections mean no specialist tooling is required for installation, though correct thread sealant and torque practice should be observed for a leak-free joint at rated pressure.
