Genebre 2455 – Flanged Swing Check Valve PN16

The Genebre 2455 is a swing-type check valve with flanged ends, designed for water lines and compatible liquids where reverse flow prevention is required without the use of an actuator. The disc opens by differential flow pressure and closes automatically when flow decreases or reverses.

Construction

Body and cover: EN-GJS-400 / GGG-40 ductile iron
Disc: EN-GJS-400 with EPDM lining
Seat: Bronze C954
Shafts: AISI 420
Bolts/nuts: AISI 304
Internal and external epoxy coating
Face-to-face: EN 558 Series 48 / DIN 3202 F6
Flanges: EN 1092 PN16

Operating Limits

Maximum working pressure is 16 bar. Operating temperature range: -10°C to +120°C. Pressure-temperature ratings decrease at higher temperatures; selection must consider actual pressure/temperature pairs, not only the PN class.

Dimensions

Available sizes: DN50 to DN300 (2" to 12"). Weights range from 9.2 kg (DN50) to 137.5 kg (DN300), relevant for pipe support and installation handling.

Applications

Suitable for water distribution, pump stations, HVAC, industrial water, and non-hazardous fluids compatible with EPDM, ductile iron, and bronze. Not recommended for fluids that attack EPDM or cause seat fouling.

Selection Considerations

DN selection should account for flow rate, pressure drop, minimum velocity for stable disc opening, and risk of water hammer. Installations near pumps or elbows require assessment of turbulence, as disc may oscillate under unstable flow.

FAQ

Does it have a spring?
No spring is specified; operation is swing check type only.

When is the 2455 selected?
For PN16 flanged lines requiring a swing check valve with ductile iron body and EPDM-lined disc.

Certificates

GENEBRE, S.A. has implemented a quality management system to control the designing and manufacturing of fluid control valves, as well as the distribution of home and public taps.

This system complies with the requirements of the current international UNE-EN-ISO 9001:2015, certified by the prestigious German certification organization TÜV Rheinland.

In 2000, GENEBRE began to comply with the European Business Excellence Model, more commonly known as the EFQM. As a result, in 2003, the Catalan Regional Government awarded us with the Quality Award. This new system enables us to ensure the quality of GENEBRE's products and also to offer added value to our clients.

In 2012, we obtained the certification for the Environmental Management System. This system is certified according to the UNE-EN-ISO 14001:2015, also by TÜV Rheinland. GENEBRE QUALITY AND ENVIRONMENTAL POLICY
