Keeping the Future Flowing – GEMÜ Valve Technology

Published: 29th April 2026 | Issue 104

Innovative. Customer-focused. Passionate. As a global specialist in valve, measurement and control systems with over 60 years of experience, GEMÜ combines precision with innovative strength to deliver engineered solutions for demanding process environments.

In June, the Great Britain subsidiary will be celebrating its 45^th anniversary, a milestone built on long-standing customer relationships and a commitment to reliability. Based in Warrington, with product specialists across Great Britain, the team provides expert technical support from specification and installation through to commissioning and aftersales service to help customers keep critical infrastructure flowing. Not only today but also tomorrow and beyond.

Technology leadership and pioneering spirit

GEMÜ continues to set new industry standards through technology leadership driven by customer needs. This approach is embodied in the new GEMÜ Product Generation, a modular valve platform developed using advanced manufacturing methods and designed for maximum flexibility, reliability and ease of maintenance.

The GEMÜ Product Generation includes four valve solutions and two automation components:

GEMÜ D40 – high-performance pneumatic diaphragm valve
GEMÜ D41 – quick-maintenance diaphragm valve with EasyLock technology
GEMÜ S40 – pneumatic globe valve with angle seat and straight seat designs
GEMÜ P40 – efficient tank bottom valve with PD technology
GEMÜ 12A0 – intelligent electrical position indicator
GEMÜ 44A0 – multi-functional combi switchbox

Innovation at GEMÜ also extends to digitalisation. The GEMÜ App and CONEXO asset management system enhance plant operations by enabling condition monitoring, efficient data collection and predictive maintenance to help prevent disruptions and costly downtime.

The GEMÜ App provides instant access to documentation, datasheets, certifications and maintenance instructions. When paired with compatible electrical positioners and process controllers, valves can even be operated via Bluetooth.

GEMÜ CONEXO uses RFID technology embedded in valve components to provide instant on-site access to equipment data using the CONEXO pen. This simplifies maintenance tasks while enabling electronic documentation and traceability—particularly beneficial for skid builders, OEMs and operators managing complex systems.

Precision flow control with GEMÜ globe valves

At CHEMUK, GEMÜ will showcase the new product generation on Stand E20, alongside a working model of the GEMÜ S40 globe valve.

The pneumatically operated GEMÜ S40 is designed for the most demanding industrial applications requiring precise and stable flow regulation, including high-purity processes such as battery manufacturing and pharmaceuticals. The standardised interfaces allow wearing parts to be replaced quickly, reducing maintenance time and downtime.

The actuator design features top-mounted control air connections, eliminating the need for alignment during installation. A transparent optical position indicator protects against dirt and dust, while a plastic piston sleeve improves sliding properties and reduces stick-slip behaviour—resulting in improved control accuracy and reduced wear.

Enhancing efficiency with GEMÜ butterfly valves

Also on display will be the GEMÜ R481 butterfly valve, fitted with the GEMÜ 12A0 intelligent electrical position indicator.

With bubble-tight sealing in accordance with EN 12266-1 / P12 leak rate A, GEMÜ butterfly valves offer reliable performance combined with a compact, modern design. Available in a wide range of materials, accessories and certifications including WRAS and DVGW, they are ideally suited for demanding applications such as water treatment and industrial process systems.
