M30 - Series Dome-Loaded Pressure Maintaining Valve
High-flow dome-loaded valve providing stable inlet pressure control in demanding applications.
M30 - Series Dome-Loaded Pressure Maintaining Valve
The M30 Series dome-loaded pressure maintaining valve delivers precise control of upstream pressure in high-flow and low to medium-pressure applications. Its balanced design ensures consistent regulation, preventing overpressure conditions where relief valves may be insufficient. Available with internal or external dome loading, it offers reliable performance without requiring a pilot regulator for gas service. Constructed from stainless steel or nodular iron, it withstands harsh environments while supporting a wide range of liquid and gas media. Leak-tight sealing, multiple elastomer options, and compatibility with various system configurations make it ideal for compressors, filtration, and pump control applications.
Balanced design ensures accurate and repeatable pressure regulation.
Durable construction provides reliability in demanding environments.
Internal/external dome loading for versatile system integration.
