Application
The Marine Cast Steel ZZVP Self Operated Micro Pressure Regulator is a robust pressure control component engineered for marine systems requiring stable micro-pressure management without external power. Crafted from high-strength cast steel, it excels in withstanding mechanical stress, moderate temperature fluctuations, and the general wear of marine environments, making it ideal for handling non-corrosive or mildly corrosive media like regular seawater, fresh water, standard marine fuels, or steam. Its ZZVP self-operated design enables automatic, precise regulation of micro-pressure, ensuring consistent system performance, while the material’s durability and cost-effectiveness make it a reliable choice for general marine piping systems—such as auxiliary equipment circuits, cooling systems, or non-aggressive fluid transfer lines—where corrosion resistance is not a primary requirement.
