Genebre 2448 Foot Check Valve DIN PN16

The Genebre 2448 is a flanged foot check valve designed for installation at the pump suction line inlet. It integrates a check valve and inlet strainer, maintaining liquid column after pump shutdown and restricting entry of larger particulates. Flange connection conforms to DIN 2501 PN16.

Construction

• Body, disc, strainer, and handle: stainless steel 1.4408 / CF8M.
• Bolts and nuts: stainless steel AISI 316.
• Seat sealing: FKM / Viton.
• Gasket: PTFE.
• Manual drain arrangement for line evacuation.

Operating Limits

Maximum working pressure is 16 bar. Nominal temperature range: -30 °C to +180 °C. Pressure–temperature curve indicates derating at elevated temperatures; selection should not rely solely on PN16 rating when operating near upper thermal limits.

Dimensions & Hydraulic Data

Available in DN50 to DN200 (2"–8"). Minimum opening pressures are low, approx. 15–21 mbar per DN, relevant for suction lines where available NPSH and inlet losses must be controlled.

Typical Applications

• Pump suction from tanks or sumps
• Potable water, industrial water, and compatible fluids
• Installations requiring suction line priming retention
• Applications needing stainless steel construction and FKM sealing

Not suitable for fluids with high solids content that may obstruct the inlet strainer.

FAQ

When is a foot valve preferred over a standard check valve?
When non-return function is required at the lowest suction point and integrated straining is necessary.

What data is required for selection?
DN, flow rate, temperature, medium, suction lift, pipe material, and available NPSH.
