1. Manufacturer Profile

GENEBRE stainless steel ball valve AISI 316 BSP thread

GENEBRE – a Spanish industrial valve manufacturer with over 60 years of experience. Today, GENEBRE components are installed in water supply, energy, food processing and chemical industry facilities across more than 70 countries worldwide.

The stainless steel valve range was designed specifically for demanding industrial conditions – where corrosion, temperature fluctuations and continuous pressure create real operational challenges. The AISI 316 alloy with molybdenum ensures longevity in chloride, saline and aggressive media environments.

Every valve enters the European market with a CE mark under the PED 2014/68/EU Directive – document-backed compliance mandatory for industrial facilities across the EU.

2. Construction – 2-piece full bore ball valve

The 2-piece full bore body is a standard industrial construction that allows maintenance without removing the pipeline, while ensuring minimal pressure drop due to full bore passage.

Construction type

Parameter Characteristic Practical benefit
Body parts 2-piece body Can be disassembled without removing the pipeline
Bore Full bore ID = pipe DN, minimal pressure drop
Operation 90° ball rotation Fast on/off, suitable for actuators
Actuator mount ISO 5211 flange Direct mounting with electric or pneumatic actuators

Materials

Component Material Note
Body AISI 316 (1.4408 casting) Cast alloy
Ball AISI 316 (1.4401) Polished, contact with PTFE seat
Thread / connections AISI 316 —
Seal (seat) PTFE Chemically resistant, food-grade media compatible
Stem AISI 316 —
AISI 316 vs AISI 304
The 316 alloy contains 2–3% Mo (molybdenum) – significantly higher resistance to pitting corrosion in chloride environments. Always specify AISI 316 where the media contains chlorides, saline solutions or marine conditions apply.

3. Operating Parameters

Parameter Value
Nominal pressure PN 63 (threaded DN 8–50)
Operating temperature –20 °C to +180 °C (PTFE seat)
Media Water, steam, air, oil, industrial fluids, drinking water
Connection BSP (ISO 228) or NPT thread
DN range DN 8 – DN 50 (threaded series)
Actuation Manual / actuator-ready (ISO 5211)

4. Technical Standards and Certifications

Standard Scope Relevance
PED 2014/68/EU CE marking Mandatory for most industrial installations in the EU
EN ISO 228 BSP thread standard Compatibility with European piping systems
ISO 9001 Quality management system Process control guarantee
EN 331 Gas valves Verify per specific model

Drinking water suitability

GENEBRE declares that its valves and taps are suitable for use with drinking water. Application areas include: water supply infrastructure, food and beverage industry, hotels, hospitals and schools.

5. Installation and Operating Notes

1
 On/off service only – this valve is not designed for throttling or flow regulation. Use dedicated control valves for flow regulation.
2
 PTFE seat limits – resistant to most industrial media, but not suitable for concentrated acids or alkalis. Alternative: RPTFE or metal seat.
3
 Actuator mounting – before assembly, verify the ISO 5211 flange size matches the actuator manufacturer's specification.
4
 Threaded connections – use PTFE tape or anaerobic sealants appropriate to the system media and operating pressure.
5
 High temperature – above +130 °C, verify the maximum PTFE seat temperature rating in the specific series datasheet.

6. Application Areas

Industry Suitable media Additional requirements
Water supply and wastewater Water, drinking water Drinking water certificate required
Food and beverage Water, CIP solutions, brines Verify EC 1935/2004 compliance per series
Industrial processes Steam, air, oil, hydraulics Standard PN 63 version suitable
Marine / outdoor Condensate, moisture, saline solutions AISI 316 mandatory – not AISI 304

7. Suitability – Engineer's Assessment

✓ Recommended

  • General industrial systems: water, air, steam up to PN 63
  • CE marking and European documentation required
  • Drinking water systems (with certificate verification)
  • Price/quality optimised installations

Requires additional assessment

  • ATEX zones – certified actuator required (II 2G/D)
  • Pharmaceutical (GMP) – higher validation level needed
  • Concentrated acids / alkalis – PTFE not suitable
  • Steam above +180 °C – verify metal seat series

8. Valve Selection Checklist

Before ordering, the engineer must specify the following parameters. If you have questions – info@elementa.lt – we will advise based on your system requirements.

# Parameter Question
1 Media Water, steam, chemicals, food, gas?
2 Operating pressure Max bar or PN class in the system?
3 Temperature Min/max °C during operation?
4 Connection Thread (BSP/NPT), flange, butt weld?
5 Actuation Manual / electric actuator / pneumatic?
6 Special standards Drinking water? ATEX? Food industry?
7 Material Is AISI 304 sufficient or is AISI 316 required?
