Safety Blocks - (Europe)

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)
