The block serves for fitting of components or valves.
The system shut-off cock serves for blocking of pressure lines.
The pressure relief valve protects the hydraulic accumulator from inadmissible
overpressure.It can be selected according to the application and is connected to the
accumulator shut-off block with a lead seal on delivery.
With this valve (hand wheel), the hydraulic accumulator can be manually pressure-
relieved.
This 2/2 directional seat valve enables electro-magnetic relief of the hydraulic
accumulator.
The accumulator adapter establishes the connection between accumulator shut-off
block and hydraulic accumulator.
The name plate serves for clear identification of the accumulator shut-off block.
