InterApp Group transitions to AVK Industrial Sales
24.03.2025
We are happy to announce an important milestone in the journey of InterApp Group: we are becoming AVK Industrial Sales.
The AVK Group is a globally respected, privately owned industrial group, comprising over 100 companies and renowned for its expertise in developing and producing high-quality valves, hydrants, and accessories for water applications and various industries.
Under the umbrella of AVK Industrial, we bring together the specialized strengths of well-established industrial brands, including:
- Indoil, offering high-performance ball valves,
- InterApp, with the PTFE-lined and elastomer-lined butterfly valves,
- Orbinox, a leader in knife gate valves,
- TecArtec, spezialised in high-performance desuperheaters,
- WouterWitzel, known for vulcanized, rubber-lined butterfly valves.
Some of the InterApp sales organizations - alrady renowned for offering one of the most extensive product portfolios in the industrial sector and backed by deep application expertise - will though gradually evolve into AVK Industrial sales organizations. This transformation reflects our commitment to strengthening partnerships, enhancing service, and supporting our customers with an even broader range of solutions.
What this means for our customers
The transition has already begun, with our organizations in Poland and Italy leading the way as they start operating under the AVK Industrial name by mid of this year.
In the German-speaking markets, we are working closely to unify our efforts and establish a strong DACH organization, which, like the North American organization, continues to operate under the InterApp brand. The existing sales structure of the other industrial brands in the DACH-region and North America remains unchanged.
Throughout this process, we are committed to keeping you informed every step of the way.
Looking Ahead
This transformation is an opportunity to provide full-scale valve solutions for a huge variety of demanding processes and industrial applications, offering unparalleled expertise, quality, and service to our valued customers and partners. As this represents primarily a name change for you, we will built on our strong relationship and trust that this will not mean any disruption for you.
For more information or questions about this transition, please don’t hesitate to contact your local representative.
We appreciate your continued trust and partnership as we embark on this exciting new chapter as AVK Industrial Sales.
Kind regards
