A bladder accumulator comprising a fluid port assembly, for communicating between a main housing of the accumulator and a connection arrangement of the accumulator, wherein an isolation valve arrangement is located within the fluid port assembly and is moveable between an open position for normal operation of the bladder accumulator and a closed position for isolating the bladder accumulator from a hydraulic system to which it is mounted, wherein the valve arrangement is fixable in the open position.
A method of using a bladder accumulator comprising:
- fixing the bladder accumulator to a hydraulic system via the connection arrangement;
- isolating the bladder accumulator from the hydraulic system for high pressure testing of the hydraulic system by moving the isolation valve arrangement to the closed position;
- and
- fixing the valve arrangement in the open position during normal operation of the hydraulic system.
