Valve functions

The patented cartridgeprinciple with its internalsealing structure, the contourof the seals and the special sealmaterials makes Festo valvesabsolute top performers, evenon valve terminals. They areextremely durable, highlyflexible and offer outstandingflow rates.

• Up to 100 % more flow• Smaller valves with higherflow rates for lower costs

• Higher pressure of up to10 bar for maximized energydensity and more power

• Vacuum compatible• Reversible – two pressures ata single valve at the sametime

• Very high temperature ranges•No overlap – totally reliableseparation of the air ductsduring dual pressureoperation

•Minimal leakage

Leading technology: the cartridge principle

Patented: the design, layoutand materials of the cartridgesensure their exceptionally highperformance.

Reversible: two pressures ina single valve (ports 3 and 5);exhaust air flows throughport 1.

Internal, positive-locking andmade of very stable materials:three reasons for theoutstanding sealingcharacteristics of the valves.And the main reason forextremely high flow rates.

Variant for reverse operationMPA valves can be operated inreverse (pressurization viaports 3 and 5, exhaust via 1). If,for example, a cylinder withpiston rod is operated withdifferent pressures (i.e. 3 and 5are isolated from each other),both the advancing andretracting movements aresubject to the same axial forcesdespite the different cross-sections of the surfaces(piston minus piston rod).

Advantages• Adjustment of the regulatoris independent of the valve’sswitching position

• Greater exhaust performancebecause exhaust air is notrouted through the regulator

• The regulator is subjected toless stress

• Can be combined with5/2 and 5/3-way valves

Vertical stackingAdditional function modulescan be added to each valveposition between the sub-baseand the valve. These so-calledvertical stacking functionsenable special modes ofoperation or control of theindividual valve position.
