The STAUFF permanent charge head allows accessory equipment to be mounted directly onto the gas side of a diaphragm accumulator. For accumulators already installed in a system, the pre-charge pressure must be at zero pressure, then the existing gas valve (typically a 6 mm socket head cap screw) and sealing washer fitted to the accumulator can be removed. The removed gas valve and sealing washer must then be fitted to the permanent charge head to allow normal pre-charge of the unit. The permanent charge head can then be fitted to any Diaphragm Accumulators that have a M28x1.5 gas valve connection.The STAUFF permanent charge head is supplied as standard with a STAUFF SKK-20 test coupling, which can easily allow other STAUFF accessories e.g. Safety pattern analogue pressure gauge, PT-RF pressure sensor or DIGI gauge to be fitted to the charge head.
