6420 Safety valves made of gunmetal, angle-type with threaded connections
The technical features of the valve series 642 and 645 form the basis of the extensive product range where connection flexibility and corrosion resistance take precedence. The two-part construction of the valve housing allows for various connection possibilities, specifically designed for use on the valve inlet.
The inlet nozzles and inner parts in contact with the media are made of highly corrosion-resistant stainless steel, enabling the valves to be used in an even wider range of applications.
These safety relief valves are used to protect:
- Pressure vessels / systems for neutral / non-neutral vapors, gases, and liquids
- Steam boilers and steam installations
Taking into account plant-specific regulations and using suitable valve configurations and sealing materials.
Applications include, but are not limited to:
- Machine construction
- Pump protection
- Pressure boosting systems water- / air-side
- Cooling systems
- Steam and industrial boiler systems
Safety valves are set and sealed at the factory.
