2Overview

2.1 Valve terminal MPA-C

Festo assists you in solving your automation tasks at machine level with the valve terminal MPA-C. The

modular structure of the valve terminal enables you to match it optimally in your machine or system.

The valve terminal provides the following connections:

– common ducts for supply and exhaust air

– electrical signals from all solenoid coils

The working ports (2) and (4) are provided for each valve position on the individual pneumatic manifold

sub-bases. The valves are supplied with compressed air (operating pressure and pilot pressure) via the

common channels and connections in the basic components. The exhaust air (from the valves and the

pilot exhaust air) is also exhausted via these common channels. Further components for compressed

air supply are also available, e.g. in order to supply pressure zones.

The valve terminal is equipped with current reduction. The nominal current of the solenoid coils is then

reduced after the high-current phase (switching operation). The current reduction offers the following

advantages:

– The valve terminal has a lower energy consumption,

– The power supply unit for the power supply to the valve terminal can be designed more economic-

ally, depending on the application

– The solenoid coils have lower power loss and produce less waste heat.

2.1.1 Purpose

The valve terminal from Festo is especially appropriate for the food and packaging industry. It fulfils the

requirements for the splash zone in accordance with DIN EN 1672-2:2009-07.

2.1.2 Performance characteristics

The valve terminal has the following performance characteristics:

– All external materials are safe for use with food

– Easy to clean (larger space between the valves, no sharp edges, no narrow radii, no dirty corners)

– Increased resistance to corrosion (KBK 4)

– Resistance to acid and alkaline cleaning agents

– Fulfills degree of protection IP69K

– Ease of maintenance

– Pre-mounted valves

– Central air supply

– Centrally ducted exhaust air

–Testedunit

– Modular tie rod system

– Subsequent conversion possible.
