Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Type 800 industrial branches named | Chemical and petrochemical industry, chlorine liquefaction, corn processing, among others | Crane ChemPharma & Energy — XOMOX High Performance Butterfly Valves |
| Richter NK size range | 2"-40" / DN50-DN1000 — the widest size range of any Richter valve | Richter Chemie-Technik — Butterfly Valves |
| Richter NK temperature range | -40°C to +200°C, triple sealing of stem (top + bottom, maintenance-free self-adjusting) | Richter Chemie-Technik — Butterfly Valves |
| Richter NK lining | PFA disc + PTFE body lining (optionally modified PTFE) | Richter Chemie-Technik — Butterfly Valves |
Richter's NK pairs PFA disc with PTFE body lining and triple stem sealing specifically because a butterfly valve's stem penetration is the leak path a lined valve has to engineer around — a single-seal stem on a fully lined body is the weak point that undoes the rest of the chemical resistance.
