Products / Parker / Cylinders and Actuators / Safety Blocks
Parker Olaer has developed a complete range of Accumulator Safety Blocks for all standard and special applications. An accumulator safety block provides a safe solution for accumulator maintenance and operation.
Parker carbon and stainless steel safety blocks include features to
make the installation, operation and maintenance of hydraulic
accumulators convenient and safe. For example, the safety block can
be used to isolate or shut down the accumulator if there's a leak or
for general maintenance. The bleed facility allows the accumulator
to be conveniently drained and the integrated hydraulic relief valve
minimises over-pressurisation.
Safety blocks are installed on the oil side of most hydropneumatic
accumulators.

Function:
The basic function of a safety valve/ shut-off block consists of:
• Manual isolating valve to isolate the accumulator from the circuit
for all the safety blocks (also drain function for DI 10 model
)
• Manual drain valve for decompressing the accumulator for all
models (also isolating function for DI 10 model) (Electrical control
optional )
• A pressure relief valve EC with poppet calibrated to the maximum
service pressure of the accumulator (pressure on request)
It must not protect hydraulic circuit
• Pressure tapping port (M)
