Sub-Bases

Festo Sub-Bases

Festo sub-bases provide the foundation for valve assemblies, enabling seamless integration of pneumatic valves into manifolds or valve terminals with standardized interfaces. These units are engineered to support multiple valve positions, provide secure mounting, and simplify installation, maintenance and system expansion.

They are compatible with a wide range of valve types and functions, and are optimized for repeatable alignment, standardized porting, and modular assembly in automated systems.

⭐ Important: Sub-bases ensure consistent valve mounting, streamlined connection of pneumatic circuits, and minimal downtime thanks to modularity and standard interfaces.

Design & Functionality

Sub-bases act as the mechanical and pneumatic interface between the valve body and the overall system. They provide:
• Multiple valve position accommodation (depending on series)
• Standardized port arrangement for compressed air supply, exhaust and valve outlets
• Robust mounting features (plate, rail or manifold) for stable installation
• Options to include blanking plugs, silencers, or fittings on unused ports
• Simplified valve replacement or servicing thanks to modular interface

Total Crossed Beams

(Applied to the functional coverage of sub-base families)
With a variety of sizes and flow capacities, these sub-bases ensure full operational coverage of valve assemblies — from compact single-station mounting to large valve banks. They cater to different widths, flow rates and valve types, allowing a broad spectrum of pneumatic control designs.

Beam Pitch Options

(Translated as: width / flow / number of modules / connection types)
Festo offers sub-bases in multiple widths and flow-rate capabilities:
• Compact widths for small valve assemblies
• Larger widths for high-flow or high-position count assemblies
• Various nominal widths (e.g., 26 mm, 42 mm, 54 mm in VABP series) 
• Different port sizes (G1/8, G1/4, G3/8) and pilot supply options 
• Accessory options for blanking, silencing, exhaust control for switch-off functions 
⭐ Important: The variety of widths and porting options means the sub-base can be tailored for compact installations or high-performance valve banks.

Intrinsic Synchronism

The design ensures each valve mounted on the sub-base is aligned precisely in terms of mounting holes and pneumatic ports. This alignment guarantees predictable flow paths, minimal leakage, and consistent behavior across multiple valve positions. Optional accessories like blanking plugs or exhaust air control valves support safe or controlled shutdown sequences. 

Operational Advantages

• Modular system enables fast assembly of valve banks and simplified maintenance.
• Standard interfaces reduce ordering complexity and support global compatibility.
• High-flow variants support demanding pneumatic applications with many valves in one manifold.
• Accessories (blanking plugs, silencers) allow customisation of unused positions and help maintain efficiency and cleanliness.
• Durable materials and design support industrial use and long service life.

Applications:
Machine automation, packaging lines, handling systems, pneumatic distribution networks, valve terminal assemblies, retrofit installations where standardized valve banks are preferred.
