1. Field Level: Mechanical Process Valves

Festo delivers robust media valves designed to manage demanding physical fluids, extreme operating temperatures, and sanitary requirements. 

• Angle Seat Valves (VZXA & VZXF): Modular, heavy-duty stainless steel or brass valves built to handle high dynamic forces and clean or abrasive media with up to 100 million switching cycles. 

Ball & Butterfly Valve Assemblies: Completely pre-assembled configurations (such as the KVZA butterfly assembly) optimized for harsh industrial liquids and gases. 

2. Actuation & Control Level: Actuators, Positioners & Pilot Valves

To manipulate the mechanical process valves, Festo integrates specialized field units that translate pilot signals into high-torque motion. 

• Quarter-Turn Actuators (DFPD & DAPS): The DFPD series uses a compact rack-and-pinion combination providing a torque range from 10 to 2,300 Nm. It is built for double- or single-acting setups and functions reliably in extreme environments from -50°C to 150°C.

• Linear Actuators (DFPI): Equipped with an integrated displacement encoder, optimized for regulating guided linear movements like knife gate valves or flue gas dampers.

• Electro-Pneumatic Positioners (CMSH & CMSX): Highly accurate closed-loop control positioners that monitor real-time flow variables and continuously adjust the process valve angle.

• NAMUR Pilot Valves (VSNC): Specialized directional spool valves that mount directly to quarter-turn actuators, featuring explosive-proof (Ex-ia, Ex-m) coils for hazardous environments. 

3. Control and Operation Level: Decentralized Valving & Remote I/O

At the top of the field layer, Festo aggregates signals and fluid power into open-protocol cabinet and fieldbus control topologies. 

• Modular Valve Terminals (VTUX & MPA): Multi-station manifolds designed to control rows of pilot lines concurrently, reducing localized tube runs and panel footprint.
