APPLICATIONS - Designed for cylinder regulator applications. - Ideally suited for pure, inert and mildly corrosive gas applications requiring a very stable outlet pressure together with a very sensitive set up of this outlet pressure. KEY FEATURES - The D 235 regulator is based on the S 20 proven bellow technology. - Accurate pressure control for reliable service and guarantees a stable outlet pressure due to the combination of the diaphragm and bellow technology. - Compact and lightweight design. - Can also be equipped with a needle or shut off valve at the outlet.1
