Tester and pressuriser VG U, VG R and Pressure regulatorsThe universal VG U and VG R tester and pressuriser unit is
indispensible for checking, charging and draining the most commonly used
hydraulic accumulators available on the market.

It is screwed to the pressurizing valve on the accumulator and connected to the
nitrogen source using a high-pressure hose that is fitted with a
pressure-reducing valve, e.g. from our DRV range.If the nitrogen only needs to be monitored or reduced, no hose is
required.The charging set VGU is an indispensable instrument for the
verification, pressurization and nitrogen bleeding of most of the hydraulic accumulators
available on the market. The standard set is delivered in a storage case
containing the following:•             VGU universal
tester and pressurizer (end M28 x 1.50).•             Pressure gauge
kit from 0 to 25 bar.•             Pressure gauge
kit from 0 to 250 bar.•             Connection
adapters for inflation valves (7/8’’ – 5/8’’ – 8V1 - M28 x 1.50).•             High pressure
hose, 2.5 m long, for connecting to a nitrogen source.•             Hexagon socket
screw key 6mm.•             Jackets of
replacement joints.•             Operating
instruction in French, English, German.Note: On request, the following options are available:•             Pressure gauge
kits with different scale divisions: 63mm with glycerol bath back end G1/4’’
cyl. equipped with direct gear forMinimess ® connection. Scale divisions 0-10, 0-60, 0-100, 0-400,
with accuracy class 1.6%.•             High pressure
hose of different length with adapters for nitrogen bottles from various
countries (specify country), at each end with afemale swivel coupling G1/4’’ for connecting to the inflation
port.Maximum working pressure: limited by the maximum operating
pressure of the installed hydraulic system, pressure limited to 400 bar
