About Aventics
Aventics Pneumatic & Fluid Control Systems by EmersonEmerson
Aventics, an Emerson company since July 2018, is a global leader in pneumatic components and fluid control systems serving factory automation, machine building, material handling, and industrial process control applications across 100+ countries. As part of Emerson's smart manufacturing division, Aventics combines advanced pneumatic technology with digital connectivity for Industry 4.0 systems.
Aventics manufactures directional control valves (Series AP poppet valves with aluminum housings and multiple actuation options), proportional pressure/flow control systems for dynamic load management, ISO 5599 Series 511/512/513 air preparation units (filtration, regulation, lubrication up to 5,200 L/min flow capacity), rodless cylinders (RTC series with oval pistons for high-load applications), and complete valve systems for panel-mount or manifold integration.
The Series AP directional control valves offer universal automation solutions with ported actuation (roller, lever, pedal, push-button, plunger), robust spool-and-sleeve technology rated up to 560 bar, and coil configurations from 24VDC to 240VAC. Aventics proportional technology enables real-time adjustment of system pressure and flow in response to variable operating conditions, optimizing machinery efficiency and reducing energy consumption.
RTC rodless cylinders feature space-saving compact design with adjustable pneumatic cushioning, sealed bearing surfaces for low friction, and rated load capacities suitable for high-precision linear automation in assembly lines, pick-and-place systems, and heavy-duty pressing applications. All Aventics components meet ISO 4401 and international pneumatic standards for cross-compatibility with system integrators' panel layouts.
ChatMRO's AI instantly matches your automation flow rate, pressure rating, actuation method, and mounting style to the right Aventics valve, cylinder, or air prep unit. No part number hunting—describe your machine's pneumatic function and we surface inventory with engineering specs and lead times in seconds.

Frequently asked questions
What's the difference between Aventics Series AP and CMS directional control valves?
Series AP poppet valves deliver universal automation control with aluminum ported bodies, multiple actuation options (solenoid, manual, pilot), and flow ratings up to 400 L/min in compact footprint. Series CMS systems are integrated manifold-mount directional valve stacks optimized for panel assembly and feature integrated ISO cavity ports, ideal for OEM machine builders requiring embedded pneumatic circuits with reduced external tubing.
When should I use an Aventics RTC rodless cylinder instead of a standard air cylinder?
RTC rodless cylinders are ideal when machine space is severely constrained, when load capacity must exceed standard cylinder rod ratings, or when your application requires smooth stroke motion with minimal friction. RTC's oval piston design distributes load across a larger bearing surface than conventional rods, making them superior for high-load pressing, clamping, and linear indexing where rod buckling or deflection would occur with standard cylinders.
How does Aventics proportional valve technology improve system energy efficiency?
Proportional valves continuously adjust spool position based on electrical input signal, eliminating the on-off dead-zones of directional control valves and matching system pressure/flow precisely to instantaneous demand. This prevents wasteful pressure relief losses and reduces heat generation, often cutting pneumatic energy consumption by 20-40% in applications with variable load cycles, making them ideal for energy-conscious manufacturing.
What flow rating should my ISO 5599 air preparation unit have?
Flow rating must exceed your downstream pneumatic actuators' peak flow demand by 15-20% for stable regulation. A typical automated assembly line drawing 200 L/min peak requires a Series 512 (250-300 L/min nominal). Aventics air prep units are rated incrementally: 511 (150 L/min), 512 (250-300 L/min), 513 (up to 5,200 L/min for high-volume factory circuits). Oversizing causes sluggish response; undersizing causes pressure drops during peak demand.
Are Aventics pneumatic components compatible with non-Emerson system integrators and OEM automation platforms?
Yes, all Aventics valves, cylinders, and air prep units are built to international ISO 4401, ISO 5599, and ISO 6162 standards for cross-platform compatibility. They work seamlessly with SMC, Festo, Parker, and other leading pneumatic suppliers' components in mixed-brand automation systems and can be integrated into existing machine control logic via standard 24VDC/240VAC solenoid coils.
