The GREGGERSEN D-QR-O2-200-0/25 is a heavy-duty industrial gas pressure regulator engineered for accurate downstream pressure control in oxygen and technical gas service. It operates as a direct-acting, spring-loaded diaphragm regulator, with a balanced valve trim that maintains stable outlet pressure independent of inlet pressure fluctuations and flow demand.
