NEWCO API 602 Globe Valves: Engineering Overview, Materials and Application
NEWCO shut-off valves, designed and manufactured by Newmans Valve LLC (USA), are a key element in ensuring the safety and efficiency of technological systems. The product line supplied by EV Group China includes valves, vents, and gates, engineered in strict accordance with industry standards for applications in the oil and gas, energy, and petrochemical industries. The design of NEWCO valves is calculated to operate under conditions of extreme pressures and corrosive-active media, which guarantees trouble-free operation and stability of production cycles.
Globe valves, manufactured according to API 602 standard, are forged products of small nominal diameters (DN), intended for critically important sections of pipelines where a high degree of tightness and the possibility of precise flow throttling are required.
Engineering Purpose
The main function of the Newco API 602 globe valve is complete hermetic shut-off (on/off), as well as precise regulation (throttling) of liquid and gaseous working media flows in systems subjected to significant thermal and cyclic mechanical stresses.
Constructive Designs of Bodies according to API and ASME Standards
EV Group China supplies NEWCO valves in various constructive designs, optimized for specific tasks and standards:
- Forged bodies according to API 602 (nominal diameter: 1/4" – 2").
- Cast bodies according to API 623 (nominal diameter: 2" – 24").
- Pressure Seal designs according to ASME B16.34 (nominal diameter: 2" – 24").
- Corrosion-resistant designs made of austenitic and duplex steels according to API 603, API 602, and ASME B16.34 (nominal diameter: 1/4" – 12").
- Straight-through Y-pattern valves according to ASME B16.34 specification (nominal diameter: 2" – 24").
Types of Pipeline Connections and Pressure Classes
The configuration of NEWCO API 602 shut-off valves is selected based on design requirements for installation and operating pressure in the system:
- Threaded (NPT/BSPT): For nominal bores from 1/4" to 2", designed for pressure classes Class 800–4500.
- Weld-end (SW/BW): Socket Weld or Butt Weld connection for diameters from 1/4" to 2" at pressure classes Class 800–4500.
- Flanged (RF/RTJ): For diameters from 1/2" to 2" and pressure classes from Class 150 to Class 2500, with various types of sealing surfaces.
Specification of Body and Internal Component Materials
EV Group China ensures the supply of NEWCO valves made from materials that meet NACE and API requirements for various working media and temperature regimes:
| Material | Application |
|---|---|
| Carbon steel ASTM A105 | Standard non-aggressive media |
| Alloy steels ASTM A182 (F1, F11, F22, F5, F9, F91) | High-temperature processes and high-pressure systems |
| Stainless steels ASTM A182 (F304/F304L, F316/F316L) | Chemically active media |
| Duplex and Super Duplex steels ASTM A182 (F51, F53) | Aggressive conditions, including marine environments |
| Inconel 625, Hastelloy C-276 alloys | Extreme temperatures and highly aggressive media |
Key Areas of Industrial Application
NEWCO API 602 globe valves are the standard for critical units in the following industries:
- Oil and Gas Industry: Shut-off and control units on main and technological pipelines, metering units, flare systems.
- Oil Refining and Petrochemicals: Cracking, hydrotreating, polymerization systems; reagent supply and product discharge lines.
- Upstream: Wellhead equipment (Christmas tree), manifolds, formation water injection systems.
- Energy: Feedwater circuits, high and supercritical pressure steam lines, bypass systems at thermal and nuclear power plants.
- Cryogenic and LNG Projects: Systems operating with liquefied gases at low and ultra-low temperatures (special design required).
Highly alloyed materials and precision machining of sealing surfaces ensure the resistance of NEWCO valves to sulfide stress cracking (SSC), high temperatures, and thermal cycling, guaranteeing a tightness class "A" according to GOST 9544-2015 throughout their service life.
