M51 - Dome-Loaded Pressure Maintaining Valve
High-pressure dome-loaded valve ensuring stable upstream pressure control in critical applications.
Balanced design ensures stable and repeatable pressure control.
Stainless steel construction enhances durability in harsh conditions.
Internal/external dome loading for flexible system integration.
Features
The M51 dome-loaded pressure maintaining valve provides precise upstream pressure control for high-flow and high-pressure applications. Its balanced valve design ensures stable regulation, even under fluctuating inlet pressures. With internal or external dome loading, it eliminates the need for a pilot regulator in gas applications. Built from stainless steel, it offers exceptional durability and corrosion resistance in demanding environments. The M51 supports liquid and gas media, with a maximum inlet pressure of 310 barg. Leak-tight sealing, helium leak testing, and multiple elastomer options enhance performance, making it ideal for compressors, aerospace ground support, and pump pressure control systems.
