What Moves the Process Industry: WAREX Takes Stock After Powtech WAREX VALVE from Senden takes stock after Powtech Technopharm 2026 in Nürnberg: customers increasingly ask for tailor-made shut-off and control components for explosion protection, hygiene and pharma.

What Moves the Process Industry: WAREX Takes Stock After Powtech
WAREX VALVE from Senden takes stock after Powtech Technopharm 2026 in Nürnberg: customers increasingly ask for tailor-made shut-off and control components for explosion protection, hygiene and pharma. In-house manufacturing keeps response times short. Three trade fair days, numerous technical discussions, and intensive exchange with customers and partners: For WAREX VALVE, Powtech Technopharm 2026 was once again an important platform to gain first-hand experience of current developments and requirements in the process industry. From September 29 to October 1, international industry experts gathered in Nürnberg. The focus was on technologies for processing and handling powders, granules, bulk materials, and liquids, as well as solutions for pharmaceutical manufacturing. For WAREX, one key takeaway emerged above all: requirements for components and systems are becoming increasingly specific. Growing Demand for Customized Solutions In many discussions, it became clear that standard solutions are increasingly reaching their limits. Diverse media, strict requirements regarding tightness and hygiene, challenging installation scenarios, special materials, or specific explosion protection requirements make customized engineering…

WAREX - Custom Solutions for Industrial Weighing Systems For use in industrial weighing systems, WAREX Valve GmbH has developed two particularly lightweight butterfly valves in nominal diameters DN 400 and DN 500.
WAREX - Custom Solutions for Industrial Weighing Systems
For use in industrial weighing systems, WAREX Valve GmbH has developed two particularly lightweight butterfly valves in nominal diameters DN 400 and DN 500. For use in industrial weighing systems, WAREX Valve GmbH has developed two particularly lightweight butterfly valves in nominal diameters DN 400 and DN 500. The custom-designed valves are bulk-material-tight and, including their pneumatic actuators, weigh only 22 and 31 kilograms, respectively. The development began with a customer’s request to reduce the weight of the components used in their weighing system as much as possible. At the same time, the system had to maintain the necessary sealing performance and ensure reliable operation. The aluminum valve disc plays a key role in the lightweight design. In addition, the entire valve assembly was designed for exceptionally smooth operation. The resulting low operating forces allow for the use of a comparatively small and lightweight pneumatic rotary actuator. A Rotork RC240-size actuator is used. In the selected configuration, this compact actuator weighs just 4.9 kilograms and delivers a torque of approximately 300…

Control butterfly valve for the pharma industry
WAREX VALVE GmbH is expanding its product portfolio with the CST DN100 process butterfly valve, designed for demanding applications. WAREX VALVE GmbH, based in Senden, is expanding its portfolio of high-quality industrial valves with a process butterfly valve specifically developed for demanding applications. The shut-off and control butterfly valve Type CST DN100 has been designed for use in process air handling within pharmaceutical plants, combining hygienic design with precise control technology and maximum operational safety. For a current project, 7 units have already been successfully manufactured and delivered. Stainless Steel Housing Tailored to Customer Requirements A key differentiating feature of the new valve is its fully stainless steel housing made from material 1.4404. While standard butterfly valves are often made from cast materials, this solution was implemented in response to specific customer requirements using a highly corrosion-resistant stainless steel design. Especially in sensitive industries such as pharmaceuticals, where cleanliness, cleanability, and material resistance…

ChemFlyer | CST, Innovative PTFE butterfly valve for aggressive media
With its special suitability for media such as chlorine gas, hydrofluoric acid and sulphuric acid, the ChemFlyer | CST from ChemValve-Schmid fits perfectly into the valve portfolio of Warex Valve Warex Valve is known for its high-performance shut-off valves, which guarantee safety and tightness even in explosion-protected areas. Customer-specific configurations play a decisive role for the valve expert in ensuring process-optimised functionality. The cooperation with ChemValve-Schmid was therefore an obvious choice: the Swiss manufacturer has been world-renowned for its modular, PTFE-lined butterfly valves for more than 30 years. Like Warex Valve, the Swiss company relies on flexible production by its own team of employees. The ChemFlyer | CST PTFE butterfly valve is in demand internationally, is manufactured in Welschenrohr to the highest quality standards and is now also distributed by Warex Valve. Design advantages The ChemFlyer | CST offers smooth functionality when used with corrosive media and plenty of scope for modifications. These result from the advantageous design: the rounded and polished sealing surfaces of the disc reduce the torque and allow…
