Genebre 2259 Pressure Relief Valve
The Genebre 2259 is an angle-type pressure relief valve constructed from stainless steel, featuring a flanged inlet PN16/40 and a BSP threaded outlet. Designed for overpressure discharge in water, compressed air, and saturated steam systems, selection is based on required discharge flow and set pressure parameters.
Technical Specifications
- Inlet connection: Flange PN16/40 per EN 1092-1
- Outlet connection: BSP Gas per ISO 228/1
- DN: 15 to 50
- Outlet size: 1" to 2"
- Discharge orifice: 13 to 32 mm
- Set pressure: 0.5 to 25 bar
- Adjustment ranges: 0.5–6 bar and 6.1–25 bar
- Max. allowable body pressure: 40 bar
- Operating temperature: -20°C to +200°C
- Body / cover / flange: Stainless steel 1.4408 / CF8M
- Disc: AISI 316 with PTFE seat
- Spring: Stainless steel AISI 302
Difference from Genebre 2258
The 2258 model is fully threaded. The 2259 is specified where a flanged inlet is required, such as on vessel nozzles, manifolds, or lines where mechanical stability and secure mounting are critical compared to threaded connections.
Applications
Typical uses include auxiliary water networks, compressed air systems, small saturated steam lines, stainless steel skids, and equipment protection where a flanged connection is specified. Flow curves are provided for water at 20°C with 25% overpressure and for air/saturated steam with 10% overpressure.
Selection and Maintenance
Sizing requires specification of medium, temperature, set pressure, discharge flow, backpressure, and DN. PTFE seat ensures tight shutoff but requires clean media; particulates, salts, or condensate may affect resealing after relief events. Periodic inspection is recommended for reliable operation.
Description
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
