www.beaumanor.com Safety Blocks The BS range of safety blocks combines all the features necessary to protect, isolate and discharge a hydraulic accumulator.

8 Safety Blocks The BS range of safety blocks combines all the features necessary to protect, isolate and discharge a hydraulic accumulator. In four sizes, the BS10 and BS20 feature a 90º movement shut off valve that also simultaneously discharges the accumulator to tank, whilst in the larger BS25 and BS sizes the discharge is controlled by a separate flow control valve. Discharge can also be instigated by a solenoid valve. The safety blocks have DBDS CE certified pressure relief valves fitted as standard Technical data Max Pressure 420 bar Nominal Internal Passage Diameter 10mm, 20mm, 25mm or mm Working Temperature 20 to +80ºC Viscosity Range 10 to 400 c St Max recommended Contamination Level 21/19/16 Shut off valve ball type Pressure Relief Valve DBDS 10 Discharge Valve manual or dual manual and electric Mounting position any Block and valve material carbon steel as standard Seals nitrile standard Nominal flow rates to system ( ΔP=1.5 bar): (consult the technical team for others) BS10= 40l/m, BS20=190l/m, BS25=240l/m and BS=400l/m Please note that with the BS10 and BS20, during discharge all three ports (P, A and T) are momentarily interconnected. Also note that the ball valves should be either fully open or fully closed and should not be used as flow control valves.
