The L45 is a robust, spring-loaded pressure maintaining valve designed for accurate inlet pressure control in low and medium-pressure applications. Its balanced design ensures stability, while manual adjustment allows precise regulation. The L45 is built for durability, featuring heavy-duty construction that withstands harsh environments. Available in carbon steel or stainless steel, it offers broad compatibility with various media, including gases and liquids. With outlet pressures up to 70 barg, it is ideal for compressor systems, pump pressure control, and research applications. Leak-tight sealing and multiple elastomer options enhance reliability across industrial and laboratory environments.
