2 FAWCETT CHRI STI E Safety Block s Carbon & Stainless Steel Why use a safety block? Accident prevention authorities recommend the fitting of a pressure relief valve to gas loaded hydraulic accumulators. The OLAERFawcett Christie range of carbon steel safety blocks include features to make the installation, operation and maintenance of gas loaded hydraulic accumulators convenient and safe. Carbon Steel (345 Bar) Pressure Maimum working pressure: 345 bar Materials Carbon steel. All blocks are fully tested. Seals Nitrile fitted as stan dard. Viton an d other options also available. Connections Pressure gauge connection (M port). Wide range of adaptors for accumulator connection. All G threads (BSP) to BS P erformance data available. Other Pressure relief valve for the protection of accumulator. Manual dump to tank valve as standard. Optional additional electomagnetic dump to tank valve.
