FPS250 Charging Kit, 8VI-ISO 4570, Gas Valve Version 4


To maintain system performance, it is recommended that the gas precharge pressure in your accumulators be checked regularly. A loss in the gas precharge pressure will cause a drop in the hydraulic system performance and could cause damage to the accumulator bladder, diaphragm, or piston.

The FPS charging unit allows hydro-pneumatic accumulators to be charged with nitrogen. For this purpose, the charging kit is connected to a commercially available nitrogen bottle via a flexible charging hose (8 feet/2.44m).

The units also allow maintenance personnel to check the current gas precharge pressure of an accumulator. The FPS kit includes a gauge, check valve in the charging connection, and a manual bleed valve with a T-handle.

Operating and installation instructions are included with each charging kit.
