Valves are central to many  processes. Collectively, they can have a huge impact on the effectiveness of a production.

Gerhard Unger provides a broad portfolio of diaphragm valves, butterfly valves, ball valves, check valves, regulating valves, sampling valves and specialist  valves. All of these deliver optimal performance through a simple, modular design and strict quality assurance procedure. Each valve is made using a small number of elements and the modular design allows for quick changeovers.

Each valve saves resources and energy which collectively produces savings while being better for the environment.
