Genebre 2224 Needle Valve – 3000 lbs, NPT F/F

Manual needle valve for throttling small flow rates in clean liquid or gas lines. The 2224 series is the stainless steel version with female NPT ends per ASME B1.20.1 and a maximum pressure of 3000 psi, approximately 206–210 bar.

Technical Specifications

Sizes: 1/4” to 2”
Connection: NPT female/female
Body: ASTM A479-04 Grade 316 up to 1”, ASTM A182 F316 from 1 1/4” and above
Bonnet / gland nut / packing nut: AISI 316
Stem: ASTM A182 F316
Needle: A182 F6 with nitrogen treatment
Stem packing: PTFE + graphite
Handwheel: painted cast iron
Kv: 0.25 to 5.36 m³/h, depending on size

Pressure and Temperature

The technical sheet provides pressure/temperature ratings per diameter group:

1/4”–1/2”: 3000 psi up to 260°C
3/4”–1 1/4”: 3000 psi up to 240°C
1 1/2”–2”: 3000 psi up to 200°C

For high-temperature selection, valve size must be checked, not just the nominal pressure of 3000 lbs.

Typical Applications

The 2224 is used in lines requiring local manual flow adjustment:

impulse lines and instrumentation circuits
small high-pressure bypasses
sampling of clean media
nitrogen, air, water, or compatible chemicals
installations with NPT piping standard

Not suitable as a first choice for slurries, suspended solids, or viscous products. The seat and needle have limited flow cross-section and are sensitive to particles, flow erosion, and seat leakage.

Difference from Genebre 2223

The 2224 is the NPT stainless steel version. The 2223 has similar material logic but ISO 228/1 connection. Replacement between ISO and NPT should not occur without checking thread standard, sealing method, and compatibility with existing fittings.

FAQ

Is it a control valve?
No. It is a manual needle valve for throttling. Automatic control requires Cv/Kv calculation and an actuator.

What to check before selection?
NPT size, pressure, temperature, Kv, media compatibility with 316/F316/F6, and packing/seat condition for sealing requirements.

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
