Product Description
The Festo VMPA series sub-bases are modular manifold plates for the MPA-S valve terminal system, forming the foundation of the Type 32 valve island architecture . Available in configurations for MPA1 (10 mm valve width) with 4 valve positions, or MPA2 (20 mm valve width) with 2 valve positions, these sub-bases provide both pneumatic connection and electronic module mounting . Manufactured from die-cast aluminium with CRC 0 no corrosion stress, the VMPA sub-bases feature standard M7 threaded working ports, support reversible flow direction (standard) or non-reversible with integrated check valves, and offer pressure zone separation options including channel 1 blocked variants .
Key Features & Advantages
2 or 4 Valve Positions per Sub-Base: MPA1 sub-bases accommodate up to 4 valve positions per module, while MPA2 sub-bases accommodate up to 2 valve positions per module, enabling high-density valve configurations with modular expandability
Exceptional Corrosion Resistance Class CRC 0: Rated for no corrosion stress according to FN 940070, providing maximum protection for demanding industrial environments
Wide Operating Pressure Range -0.9 to 10 bar: Suitable for both vacuum applications (down to -0.9 bar) and positive pressure systems up to 10 bar, with pilot pressure range of 3 to 8 bar
LABS (PWIS) Conformity VDMA24364-B1/B2-L: Complies with paint-wetting impairment substances standards, making these sub-bases suitable for paint shop environments and applications sensitive to paint defects
Pressure Zone Separation Options: Available with channel 1 blocked (T1 suffix) for creating independent pressure zones within the same valve terminal ; also available with separation seals for channels 1, 3 and 5 for complete pressure zone isolation
Integrated Check Valve Option (-RV Suffix): Sub-bases with RV suffix feature integrated non-return check valves for non-reversible flow applications, preventing backflow and ensuring directional control
Die-Cast Aluminium Construction: Manufactured from high-quality die-cast aluminium with RoHS compliance, offering excellent mechanical strength, dimensional stability, and long service life
Electronic Module Mounting: Each sub-base accepts an electronics module (grey for single solenoid, black for double solenoid) that defines electrical addressing and provides valve control
Compact Dimensions: Standard length of 107.3 mm across all VMPA sub-base variants, with width of 48 mm for 4-position MPA1 sub-bases and 47 mm for 2-position MPA2 sub-bases
Product Weight Range: 153 g (VMPA2-FB-APF-2-1-S0) to 190 g (VMPA1-FB-AP-4-1-RV) depending on valve size and configuration
M7 Threaded Working Ports: Standard M7 pneumatic connections for working ports 2 and 4, ensuring compatibility with common fittings
Wide Operating Temperature Range -5°C to +50°C: Operates reliably across standard industrial environmental conditions
Interlinking Board Compatibility: Sub-bases require corresponding interlinking boards (VMPA1-FB-EV-AB for sub-base, VMPA1-FB-EV-V for pneumatic supply plate) for electrical connection between modules
Tie Rod Fastening System: Secure mounting to manifold rail using tie rods with specified tightening torque of 1.8 Nm ±10% for sub-base linking
Maximum 16 Sub-Bases per CPX Terminal: When used with CPX terminal and electric supply plate, a maximum of 16 MPA-S sub-bases are permitted per valve terminal assembly
Supply Module Compatibility: MPA electronic modules require specific supply modules; VMPA1-FB-EMS/EMG series must be powered via CPX-GE-EV system supply modules (M18 or 7/8" connectors)
Electrical Isolation Option: VMPA1-FB-EMG-... electronic modules feature complete electrical isolation between electronics and valves, enabling all-pole shutdown of valve supply voltage

Installation Notes (from Festo documentation)
Maximum 16 MPA-S sub-bases are permitted on the MPA-S valve terminal with CPX terminal and electric supply plate; without electric supply plate, maximum 8 MPA-S sub-bases are permitted
When extending a valve terminal, the sub-base must be mounted at the point where expansion is required; dismantle the sub-base or air supply plate at that location first
For multi-pin plug connection terminals, when mounting a further sub-base to the last sub-base before the right MPA end plate, the end piece type MPA must be removed from the last interlinking board
Sub-bases without pressure zone separation use standard seals; sub-bases with pressure zone separation in channel 1 require separating seals
For MPA electronic modules with electrical isolation (VMPA1-FB-EMG-...), the valve supply voltage can be switched off at all poles when used with manifold sub-base CPX-GE-EV-V or 7/8" 5-pin system supply modules
All valve and blanking plates on the sub-base must be loosened before removing the interlinking board; the electronics module must be removed from the sub-base prior to interlinking board replacement
Tightening torques: electronics module 0.4 Nm, sub-base linking 1.8 Nm, MPA1 valve on sub-base 0.25 Nm, MPA2 valve on sub-base 0.65 Nm
For CPX terminal integration, the left end plate (CPX terminal) weighs approx. 80 g; the right end plate (MPA-S) weighs 55 g
