Process Valve Units

Festo Process Valve Units

Festo process valve units integrate actuators, pilot valves, feedback modules, and sensor technology into a unified assembly engineered for controlling the flow of liquids, gases, or steam. These units are designed to simplify installation, ensure repeatability, and deliver high stability under demanding process conditions.

Built around standardized process interfaces, the units offer modularity, corrosion resistance, and easy maintainability—making them suitable for hygienic environments, continuous operation, and decentralized automation setups.

⭐ Important: Process valve units provide complete modular control, high reliability, and seamless integration with automated process systems, significantly reducing installation and maintenance effort.

Design & Functionality

Festo process valve units function by combining a process valve (such as a butterfly or ball valve) with a pneumatic or electric actuator, plus optional pilot valves, position feedback sensors, and control terminals.
This creates a full plug-and-play assembly for regulating liquid or gas flow.

Key functional elements may include:
• Pneumatic quarter-turn actuators
• Electric control terminals
• Pilot valves for switching
• Position feedback (open/close indicators or continuous sensing)
• Stainless-steel or corrosion-resistant valve bodies
• Manual override and safety shut-off options

The units ensure precise opening and closing, rapid response, and excellent media compatibility across a wide variety of industrial fluids.

⭐ Important: Integrated sensing and pilot control ensure consistent, automated switching with high repeatability and low air consumption.

Total Crossed Beams

(Applied to the functional coverage of process valve configurations)

Comprehensive performance coverage across multiple valve families—ball valves, butterfly valves, angle-seat valves, and shut-off valves.

Engineered to deliver stable flow control, reliable switching cycles, and durable operation even under pressure fluctuations or continuous media exposure.

Designed to maintain operational capability regardless of pipe size, medium type, or mounting orientation.

Beam Pitch Options

(Translated as: actuator sizes, valve types, build variants)

Multiple configuration choices for adapting the valve unit to different processing requirements:

• Quarter-turn or linear actuators
• Ball valves, butterfly valves, or angle-seat valves
• Stainless steel, brass, or polymer valve bodies
• On/off or proportional control
• Pilot-controlled or electrically actuated switching
• Optional feedback modules for digital or analog monitoring

Additional options include:
• High-temperature variants
• Hygienic/wash-down compatible housings
• ATEX-compliant versions
• Manual override mechanisms
• Communication modules for fieldbus integration

⭐ Important: Multiple valve and actuator combinations ensure optimal performance for high-pressure, hygienic, and corrosive media applications.

Intrinsic Synchronism

Actuator and valve components are designed to operate in synchronized motion, ensuring consistent and accurate switching across thousands of cycles.

Optional guided motion and sensor feedback increase precision, allowing the unit to maintain exact positioning even in vibration-prone or high-flow environments.

Ensures stable performance and repeatable process control over long operational periods.

Operational Advantages
