IMI Maxseal
M30 - Series Dome-Loaded Pressure Maintaining Valve
High-flow dome-loaded valve providing stable inlet pressure control in demanding applications.
Balanced design ensures accurate and repeatable pressure regulation.
Durable construction provides reliability in demanding environments.
Internal/external dome loading for versatile system integration.
Features
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.
