Parker Hannifin has launched the SBA Series, a new range of multi-function accumulator safety blocks.
The products are designed to be used in a wide variety of critical hydraulic applications and have been developed simplify protection, isolation and discharging a hydraulic accumulator from a single unit.
Each SBA safety block incorporates shut-off, pressure limiting and pressure release function, with each being rated for use in systems operating at up to 350 bar.
The blocks include a 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 blocks are simple to install and operate and are fully compliant with the European Pressure Equipment Directive (PED) 97/23/EC.
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.
