New multi-function accumulator safety blocks from Parker Hannifin

Sept. 10, 2008 - PRLog -- Parker Hannifin, the global leader in motion and control technologies, has launched an innovative new range of accumulator safety blocks.  Called the SBA Series, the new products are designed to be used in a wide variety of critical hydraulic applications and have been developed to help minimise system build and maintenance times, reducing overall costs while at the same time improving operational safety.

By comparison with traditional safety mechanisms, which often incorporate several independent components to meet the requirements of the Pressure Equipment Directive (PED), the new products make it simple to protect, isolate and discharge a hydraulic accumulator from a single unit.  In particular, each SBA safety block incorporates shut-off, pressure limiting and pressure release functions in a compact and robust housing, with each safety block being rated for use in systems operating at up to 350 bar.

The new SBA safety block has a number of unique features, including a modular design of tamper-proof pressure relief valve that can be specified in a wide range of pressure settings.  The valve can easily be changed without needing to disconnect or remove the block, simplifying changes to system pressures and making it easier for OEMs to specify and stock component parts.  

In addition, the integrated shut-off valve allows an attached accumulator to be isolated and then safely discharged to a tank; this can be done either directly, using a lever operated discharge valve mounted on the block, or remotely by means of a separate electrically controlled discharge valve.  The latter enables accumulators mounted in inaccessible areas to be discharged easily by a plant engineer or, in an emergency, by a remote control system.

The new blocks are simple to install and operate and are fully compliant with the European Pressure Equipment Directive (PED) 97/23/EC, which requires the use of safety devices with accumulators in industrial applications. All SBA safety blocks are finished in a durable, chrome-6 free, corrosion resistant finish for long service life, and are designed for use with all types of accumulators: bladder, piston and diaphragm.  The SBA range comprises three different sizes to suit most industrial applications: the SBA10, SBA20 and SBA32, which correspond to DN10, 20 and 32 respectively. A full range of adapters is available to suit all common accumulator port sizes and styles.
