Direct acting upstream pressure relief-sustaining valve

The CSA Mod. VSM, with body in ductile cast iron and internals in stainless steel, sustains and discharges the upstream pressure regardless of variation in flow rates and downstream pressure pulsations. Thanks to the self-cleaning upstream 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.
