Gas charging and testing kits

There are typically two types of accumulator design, bladder and piston.  In both cases compressed nitrogen gas is used as a damper or energy store. Typically bladder style accumulators are used in low pressure systems and piston type in higher pressure applications. There are many manufacturers of accumulators and many different charging and testing valve connections utilised.

Ensuring that the pre-charge pressure is set correctly is important for both the correct functioning and ensuring accumulator life is not compromised. If the user tends to be careless about gas pressure and relief valve settings, or adjusts system pressures without making corresponding adjustments to pre-charge pressure, service life may be shortened and system performance compromised.

Hydrotechnik UK has developed a range of kits that suit over 95% of the worlds accumulator types and valve connections. Specific kits for Minimess, Schrader or M28 x1.5 metric male ‘allen’ key accumulator valves are all catered for. A key aspect of the kits are the range of pre-charge testing and charging devices available. The top of the range 5401 charging device allows service engineers to safely test and charge gas accumulators under full system pressure without the loss of gas or pressure.

Hydrotechnik also supply Minimess charging and testing points to swap out standard charging valves fitted to accumulators. The benefits claimed for this are higher pressure capabilities along with lower gas leakage rates than standard valves and easy screw on/off connections that are completely safe. If Minimess valves are used on accumulators a low cost, easy to use charging device kit is available for service and maintenance.

All Hydrotechnik UK’s gas charging kits and valves are held in stock for immediate supply. Standard glycerine gauges or digital pressure gauges can also be included in the kits.
