Applications
The Valmet NDX1511 can be used in industrial process-control applications requiring intelligent valve positioning and diagnostic capabilities. The broader NDX platform is designed for applications across industries including chemical, petrochemical, oil and gas and other process industries.
The standard NDX1511 design makes this page meaningfully different from the compact NDX1510 product page and from the explosion-proof NDX1512 series.
NDX1511 vs. Other NDX Designs
The NDX family includes different enclosure/design configurations for different installation requirements.
NDX1510 — Compact design
NDX1511 / NDX2511 — Standard design
NDX1512 / NDX2512 — Explosion-proof design
Therefore, buyers should not select an NDX controller based only on the NDX family name. The complete model and ordering configuration should be checked against the application requirements.
Selecting the Correct NDX1511
Before ordering a Valmet NDX1511, confirm the complete product code and application requirements, including the valve and actuator type, pneumatic requirements, communication requirements, installation environment and required approvals.
For replacement projects, providing a clear photograph of the existing device nameplate can help verify the requested configuration.
