SB Accumulator Safety Block
Explanation Individual Parts
Manual and Electrical Discharge Valve
The discharge valve allows fluid stored in the accumulator to be discharged to tank. All models of SB safety
block are fitted with a manually-operated discharge valve. As an optional feature, an electrical discharge
valve is available in addition to the manual valve. An electrical discharge valve should be specified where
the safety block is to be mounted in a remote or inaccessible location. Manual-only versions of the SB
safety block are denoted by an M in the model code, see page 33, while models with both a manual and
an electrical discharge valve are designated E.
Opening Handle / Locking Device
The exclusive colourflow colour-band shows drain valve status.
The colour indicates the drain valve‘s condition (open / closed).

SB Accumulator Safety Block
Pressure Relief Valve
CCP - Integral Connector Coil
The function of the pressure relief valve is to protect the accumulator in service. If pressure exceeds the
relief valve setting, the valve lifts off its seat and fluid is discharged to tank, allowing pressure in the system
to fall to a safe level.
Because of its cartridge design, the pressure relief valve can be readily replaced by a valve with a different
pressure setting, selected from the table. A new approval under PED 97/23/EC is not required following this
change. The pre-set relief pressure, in bar, is stamped onto the pressure-relief valve identification marking.
• Universal 50 / 60 Hz operation
• Waterproof coil hermetically sealed,
requires no O-rings or waterproof kits
• External plated steel flux-carrying band enables
coil to withstand severe thermal shocks without
cracking
• Conforms to DIN 43650
(AC or DC, supplied without DIN connector)
ground wire on AC only
* Resistance +/- 10% at 20°C
