Applications Hydraulic oil circuits:

• connection of hydraulic components on staticand dynamic test benches

• connections of pumps, cylinders and directionalcontrol valves

Robust, protected lockingmechanismGreat number of large cross section balls, that arecompletely insulated and that cannot clog.

Protected sealing partsSealing faces and seals protected from externalimpacts.

Protective dust capsAvailable on all models.

SBA anti-pollution hydraulic couplings ...

The anti-pollution generation A design that eliminates residual dead internalvolume:

• prevents a specific volume of oil being releasedat every uncoupling operation,

• prevents the introduction of the same specificvolume of air at every coupling operation.

Automatic operationCoupling and uncoupling in one movement, one-handed.

Reduced pressure drop The circuit is specifically designed to allow directflow of the fluid stream without breaking thestream and without any turbulence. The resultingpressure drops are very small.

Instant visual circuit identification. Fast circuit identification by coloured rings:

Applications All hydraulic circuits needing to be connectedunder residual pressure:

• hydraulic core circuits on injection press moulds

• hydraulic circuits on rolling mill trains

Connection under residual pressureLowering of the residual pressure by a central reliefvalve built into the socket valve or the plug valve.

Automatic opening of this valve allows the volumeof oil necessary for the backward movement of thevalve to be released into the hose that is not underpressure.

TightnessThe Fluorocarbon seal option is available on allmodels.

Add the code “JV” to the socket and plug part-numbers. Ex. : SBA 08.1103/JV

Connection under residual pressureOption available on SBA 08 and 12 only:

Compatibility between diameters

Situation 1: socket under residual pressure Return to tank on the plug side

- socket: add the code “PA” to the above part-numbers - plug: part-numbers on page 7Ex. : SBA 08.1103/PA + SBA 08.7103

Situation 2: plug under residual pressureReturn to the tank on the socket side

- socket: part-numbers above - plug: add the code “PA” to the part-numbers on page 7Ex. : SBA 08.1103 + SBA 08.7103/PA

Identification of the circuitsThe coloured ring option is available all on diameters:

Add the colour code to the socket and plug part-numbers:KB = blue rings KR = red ringsEx. : SBA 08.1103/KR - SBA 08.7103/KR
