Neotecha Emerson Lined Valves: Engineered Solutions for Corrosive and Aggressive Media

Neotecha valves from Emerson represent an engineered solution for flow control in extreme conditions. The key design element is a continuous high-tech lining that ensures absolute chemical inertness. This coating guarantees exceptional resistance to concentrated acids, alkalis, solvents, and oxidizers even at peak operating temperatures.

The Lined Valves series is designed for critically important processes in chemical synthesis, pharmaceuticals, and microelectronics. These valves are an indispensable solution in systems where standard metallic alloys are subject to rapid corrosion and degradation due to the high chemical activity of the working media.

PTFE/PFA Lining Design and Technology

A distinctive design feature of Neotecha valves is a monolithic protective layer of fluoropolymers (PTFE/PFA) applied to the internal surfaces. The polymer lining or static molding spray coating adheres tightly to the body, seat, and closure element, creating a seamless barrier.

This inert barrier completely eliminates contact between the metallic base and the transported substance. The perfectly smooth surface of the lining minimizes adhesion and prevents scale formation, which is critically important for product purity and simplifying CIP/SIP (Clean-In-Place/Sterilize-In-Place) procedures. This directly affects the increase in the mean time between failures and the overall reliability of the technological line.

Key types of Neotecha lined valves:

  • PFA/PTFE lined ball valves for complete flow shut-off.
  • Butterfly valves for regulating and isolating aggressive media flows.
  • Sampling systems ensuring sterility and representativeness of the sample.
