Experience the future of green hydrogen

Process valves of various types are used to control process variables such as flow rate, temperature, etc. These are often controlled by single-acting diaphragm actuators. These are often controlled by single-acting diaphragm actuators. In the classic case, the actuators - and therefore indirectly the process valves - are controlled using a positioner. These use various methods to measure the position of the actuator or valve and regulate it to the position required by the main controller.

Another control device is the so-called I/P transducer, a current/pressure transducer. This is primarily used in linear systems - but only if the position of the valve is not important for safety-related considerations. Proportional valves, such as the VPPM from Festo shown here, can take over the function of an I/P transducer. They usually outperform them in terms of control quality and even ease of operation

Secure a productivity advantage with ready-to-install process valve units or pre-assembled control cabinets. Whether you need a control cabinet for potentially explosive zones or want to simplify the maintenance of your automation components, we will support you with the needs-based planning and implementation of your solution. If safety is the focus, a central automation concept can be the ideal solution.

The functional safety requirements (SIL) can also be met with our components. You benefit from our complete solutions thanks to simplified commissioning and reduced installation work. And you receive all components from a single source - precisely matched to each other and to your requirements.
