STDA-A Permanent Charging Heads for Diaphragm Accumulators

The STAUFF permanent charge head allows accessory equipment to be mounted directly onto the gas side of an accumulator. For accumulators already installed in a system, the pre-charge pressure must be at zero pressure, then the existing gas valve 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 Acumulators that have a M28x1.5 gas valve connection. Supplied with standard SKK-20 test coupling.
