Broad portfolio for process valve automation

Do you need single components to automate process valves, or a complete, standards-compliant and repeatable automation package? Choose the approach that fits your design. Our pneumatic expertise, wide product range and practical engineering support will help you to specify products faster, integrate them smoothly and keep documentation consistent across multi-vendor configurations.

It’s your choice: on/off valves or flow control valves

For on/off valves, sensor boxes/limit switches provide reliable electrical feedback and position monitoring. For flow control, digital electro-pneumatic positioners deliver accurate performance and are easy to commissioning.

Rotary or linear motion: choose the right actuator for your application

Linear actuators are suitable for air damper control, bulk material handling and regulating flow and fill levels. Quarter-turn actuator options, including pneumatic rotary actuator variants, are ideal for ball, shut-off, and butterfly valves in demanding process environments.

Whatever you decide, standardised architectures, broad component coverage and selection support help reduce effort and complexity. You also shorten time-to-delivery with fewer redesign loops.

Your benefits:

  • Reduced engineering and documentation workload
  • A reliable second source for key automation components
  • Standardised yet flexible architectures across brands
  • Commercially viable solutions that scale across industries

Rotary actuators for precise rotary motion and high torque performance

Rotary actuators DFPD, DFPD-C, DAPS

Quarter-turn actuators DFPD are available as standalone or as part of a complete automated process valve system. The swivel direction can be configured to the left or right in order to set Fail Open or Fail Close in single-acting designs. The ISO 5211 valve interface plus NAMUR mounting make it easier to fit solenoid valves, sensors and positioners. Nickel-plated or stainless shafts add durability, while the pilot-valve re-breather function helps protect the springs in corrosive atmospheres. Options include standard, epoxy-coated and anodised aluminium housings.

Linear actuators for accurate linear motion and positioning control

Linear actuators DFPC, DFPI-NB3

Beyond quarter-turn automation, many process tasks rely on accurate linear positioning, such as for regulating flow and fill levels or controlling air dampers. Our linear actuators with ISO 5210 and 15552 interfaces combine sturdy mechanics with configuration options for on/off tasks or closed-loop control via an integrated displacement encoder. With strong protection from external influences (IP65/IP67/IP69K) and ATEX-classes, you can assemble suitable process valves that are reliable in harsh operating conditions.

Your partner for process valve automation

The success of process valve automation depends on more than just individual parts; it takes a partner who understands complete systems, industry requirements and long-term operating performance to achieve high-quality designs. From engineering and commissioning support to lifecycle services, you will have everything you need to reduce complexity, improve reliability and protect performance over time.

Compliance and standards in valve automation

Ensuring products and solutions meet compliance requirements drives your delivery. Since each requirement comes with its own standards, you may need SIL for safety functions, ATEX-certified variants for hazardous zones, and the right solutions for hygiene-sensitive areas (for example product-contact vs splash zones). These topics often overlap, so the valve assembly must meet a combination of requirements.

Standardised interfaces and all-round compatibility

Integration challenges increase cost and are time-consuming. Standardised interfaces and accessories across the complete process automation portfolio help reduce integration work. Compatibility with multiple process valve manufacturers and industry-standard mounting support flexible design, reduce engineering effort and ensure systems are future-ready.

One-stop-shopping made easy:

  • Valve to actuator: ISO 5211 for quarter-turn actuators; ISO 5210 and ISO 15552 where linear interfaces are used
  • Actuator to pilot valve: NAMUR (VDI/VDE 3845) for consistent pneumatic control integration
  • Actuator to positioner or limit switch: VDI/VDE 3845-1 and 3847-2 are widely used standards for sensor/feedback interfaces
  • Accessories: providing a standard method for mounting a wide range of components

Engineering tools for faster and more reliable production selection

Our engineering tools are designed to make product selection easier and more efficient. They support you in choosing the right configuration for your application, from selecting the correct size and rotation angle to defining functions such as double-acting or single-acting operation. In addition, you can specify material options and surface treatments to ensure products perform optimally in your operating environment. This helps you quickly identify the right solution, reduce configuration errors, and streamline your engineering process.

Digital integration into process automation systems

Seamless data exchange with the highest control level is crucial. The positioner CMSH communicates directly with third-party control systems, enabling efficient data transfer and system transparency.

Components that are designed for Industry 4.0 and IoT environments can exchange information with the central control system, thus supporting advanced diagnostics and performance monitoring. When combined with solutions such as Festo AX for condition monitoring and predictive maintenance, this creates greater visibility, improves reliability, and optimises system performance throughout the entire lifecycle.

Global delivery, availability and lifecycle support

Automation projects rely on dependable supplies and consistent support. A global presence and strong regional supply networks allow you to access components and solutions worldwide. Services throughout the product lifecycle help you manage spare parts, plan for modernisations and make technical expertise available for the entire service life of your system, across sites and for future expansions.

Proven use in regulated industries

In regulated environments such as food and beverage, chemical processing, and water and wastewater, safety, reliability and compliance are non-negotiable. Our automation solutions for process valves are designed with a clear understanding of industry standards, operational pressures and long-term performance requirements.
