The K50 Series dome-loaded pressure regulators deliver precise pressure control in high-pressure and high-flow applications. Featuring a balanced valve design, they ensure stable outlet pressure while allowing fine adjustments via dual needle valves. A flexible diaphragm separates the process media from the dome gas, ensuring media segregation. Constructed from stainless steel, the K50 Series withstands aggressive environments such as offshore, marine, and industrial gas systems. Suitable for liquid and gas media, they operate at inlet pressures up to 420 barg. Leak-tight sealing and a broad range of elastomer options enhance performance in industries such as oil and gas, mining, and steel processing.
