High capacity pressure reducing valves
Common characteristics: body and cross-head made of light alloy (to restrict weight) with chemical nickel treatment allowing them to be used with any kind of non-corrosive gas. Mod.128 is also made in bronze. Complete with high and low pressure-gauges and incorporated stainless steel filter. Large flow pressure regulators may be controlled via a pilot pressure reducing valve.
