Genebre Float Valve Type 2856N

The Genebre 2856N is a mechanical float valve constructed from AISI 316 stainless steel, designed for level control in water storage tanks. The 2856N variant differs from the standard 2856 by its connection type: it utilizes NPT threads in accordance with ASME B1.20.1, rather than ISO 228. Operation is entirely mechanical via float and lever arm, with no electrical sensor or actuator integration.

Flow Rate and Sizing

Flow rates are provided in l/h for 1–10 bar inlet pressure. For reference, the 2856N 04 1/2" delivers 2,829–8,938 l/h, while the 2856N 10 2 1/2" delivers 24,869–79,275 l/h. Valve sizing should be based on available pressure, required fill rate, and float movement clearance.

Suitable Media and Applications

Primarily used in clean or potable water tanks. For process water or chemically affected liquids, compatibility with AISI 316 and silicone must be verified.

Typical applications:

Potable water storage tanks
Auxiliary tanks in industrial facilities
Filling systems without electrical level automation
Installations with NPT piping or equipment

Difference: 2856N vs 2856

The 2856N features NPT threads and is available up to DN 65. The 2856 uses ISO 228-1 threads for smaller sizes and EN 1092 PN 10/16 flanged connections for DN 80–DN 100.

FAQ

Is the float included?
The valve is paired with a Genebre 2852 AISI 316 float, with float diameters from 90 to 200 mm depending on valve size.

What is checked during maintenance?
Inspection focuses on the silicone seat, free lever movement, scale buildup, and shut-off tightness.
