M51 - Dome-Loaded Pressure Maintaining Valve

High-pressure dome-loaded valve ensuring stable upstream pressure control in critical applications.

 

M51 - Dome-Loaded Pressure Maintaining Valve

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.

Tick   Balanced design ensures stable and repeatable pressure control.

Tick   Stainless steel construction enhances durability in harsh conditions.

Tick   Internal/external dome loading for flexible system integration.
