The NANPU series of pressure regulators are available in three port sizes: 1/4", 3/8", and 1/2". These products are made of zinc alloy, which offers several outstanding advantages. Zinc alloy is renowned for its excellent corrosion resistance, ensuring that the pressure regulators maintain their performance and appearance even in harsh environments. Its high strength and durability make the regulators reliable and long-lasting, reducing the need for frequent replacements. Moreover, zinc alloy has good casting properties, allowing for the production of precision components with complex shapes, which contributes to the precise regulation of pressure. The NANPU series pressure regulators, with their zinc alloy construction, not only provide excellent performance but also offer a cost-effective and reliable solution for various applications.
