Neles Shut-off Valves: Expert Solutions

Technical Features and Standards of Neles Shut-off Valves

Neles shut-off valves are the benchmark for reliability in automated flow control systems under high pressures and aggressive media. The equipment is designed in accordance with international standards API, ANSI, EN, and ISO, ensuring full integration into critical nodes of the oil and gas, chemical, and energy complexes. EV Group China supplies original Neles solutions, guaranteeing compliance with SIL certification, which is critical for safety instrumented systems (SIS).

Neles Classification and Model Range

The Neles product line covers a wide range of tasks — from standard shut-off to precise throttling:

  • Jamesbury Valvcon Series: Universal ball valves with floating or trunnion mounted balls. They ensure tightness according to class VI in accordance with ANSI/FCI 70-2.
  • Neles X-Stream Series: Specialized line for extreme temperatures (up to 600 °C) and abrasive media. The use of Stellite overlays increases wear resistance under intense thermodynamic loads.
  • Neles M Series (Modular Ball Valves): Modular ball valves optimized for integration with intelligent positioners.
  • Neles Globe-type Series: Straight-through globe valves designed for operation with saturated steam, condensate, and liquefied natural gas.
  • Neldisc Series: Eccentric disc valves (double/triple eccentricity) for large diameter pipelines.
  • Jamesbury Wafer-Sphere Series: Wafer-type compact valves for installation in limited space conditions.

Where We Apply

Neles shut-off valves from EV Group China are used in critical infrastructure: in crude oil primary processing plants, in chemical reagent mixing units, on high-pressure steam lines of combined heat and power plants, and in liquefied natural gas (LNG) transportation systems. Engineers choose these solutions where leaks are unacceptable and the frequency of open-close cycles requires increased seal life.

What to Clarify with the Supplier

Before placing an order with EV Group China, we recommend requesting the following package of documents: 1) Certificate of conformity for a specific batch of goods; 2) Product passport indicating seal materials (important for chemical compatibility); 3) Leakage test report according to the specified class (e.g., API 598); 4) Actuator specification (pneumatic, electric, or hydraulic) to confirm compatibility with your DCS.
