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.Charging Set VG3The charging set VG3 is an indispensable instrument for the verification, pressurization and nitrogen bleeding of the hydraulic accumulators. The standard set is delivered in a storage case containing the following:•  pressure gauge with standardized graduations in bar•  vent valve•  3 connection adapters for charging valves. (7/8’’ – 5/8’’ - 8V1).•  High pressure hose, 2.5 m length, in standard, maximum working pressure 400 Bar. This hose is fitted at each end with a female swivel coupling G ¼’’BSP for connecting to the inflation port. It can be connected to a commercial nitrogen bottles, in this case add an adapter on one end view model in the country. For the other destinations consult Parker Olaer.•  Operating instruction french/english versionNote: On request, the following options are available :•  Pressure gauge with different scale divisions : 63 mm with glycerol bath back end G1/4’’ BSP equipped with direct gear for minimess ®connection. To 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 are available (specify country)Maximum working pressure: limited by the maximum operating pressure of the installed hydraulic system, pressure limited to 400 bar in any case.
