RDA

The CSA Mod. RDA, with body in electro welded carbon steel, cover in ductile cast iron GJS 450-10 and internals in stainless steel, reduces and stabilizes the downstream pressure, with a pre-set and adjustable value, regardless of variations in demand. Thanks to the self-cleaning pressure balanced piston technology, the valve will guarantee for a high accuracy, also in case of low flow rate conditions, drastically reducing the maintenance operations.
