Corvane got its specs cited by AI engines and turned engineering prompts into RFQs
Industrial valve and actuator manufacturer. Got its spec sheets cited when engineers ask AI for valve recommendations, and turned those answers into RFQs.
“Engineers paste our spec table into their RFQs because ChatGPT pointed them to it.”
Katrin Albers, Head of Marketing, Corvane
Overview
CORVANE (industrial valve and actuator manufacturer) asked us one question: when buyers in Germany & United States ask AI “best high-pressure ball valve manufacturer for hydrogen applications”, why don’t we come up?
We ran a 60-prompt panel across ChatGPT, Perplexity, Gemini, Copilot and followed the answers into the CRM. Over Feb to Sep 2026 the ANSWER Method moved CORVANE from missing to cited.
Services: AEO, LLM-ready content, technical AEO & schema, digital PR and AI visibility & lead tracking. See the manufacturing playbook.
The challenge
- Specs locked in PDFs. Pressure ratings and materials only existed in downloadable datasheets.
- Distributors outranked the maker. Catalogue sites were cited instead of Corvane.
- Two languages. German and English pages disagreed on certifications.
What we did
