MGR calls for safety first as it launches new hydraulics range

20 September 2015

A Midlands hydraulics specialist is calling for industry hazards to be more widely acknowledged as it expands its product range with the launch of its new accumulator safety blocks, which are immediately available from stock.

MGR Fluid Power has manufactured the new range to comply with relevant safety standards including DIN EN982, together with tamper proof relief valves that conform to the Pressure Equipment Directive 97/23/EC.

Unsafe and potentially dangerous use of high pressure hydraulic tools is still a frequent occurrence across the sector. Unreliable extensions, connecting low pressure tools to high pressure tools, and careless operation of hydraulic devices are still common and create unnecessary risks. MGR's new safety block range is designed to provide an immediate shut off function in case of accumulator malfunction or as a result of poor maintenance.

To be effective, hydraulic systems must store fluid under high pressures, typically 300bar or more. One hazard comes from removing or adjusting components without releasing the pressure. Pressure can rise due to increasing accumulator gas pressure caused by fire or local heating.

MGR’s safety block range includes a vent down valve that can be deployed for system de-pressurisation before hydraulic maintenance, as well as a fast acting relief valve that prevents excessive hydraulic pressure. The valve protects both the accumulator and the pipework in the event of over-pressurisation. The entire range has been designed and manufactured to be used with various types of accumulators including bladder, piston, and diaphragm.
