431 Overflow and pressure control valves made of stainless steel, straightway form with flange connections
High flow rates at low pressure differentials. Adjustable externally during operation and adaptable for liquid and gaseous mediums; maintenance-friendly with a replaceable cartridge.
This overflow valve made of high-alloyed stainless steel combines all these advantages. Depending on the applied sealing and membrane materials, these valves can be used for neutral and non-neutral mediums.
For the protection of:
- Pumps against overload in closed circuits for neutral/non-neutral, non-adhesive liquids
For the control of:
- Systems under pressure for air, neutral/non-neutral gases, and vapors
- Industrial installations
- Power plant technology
- Pump systems
- Machinery engineering
- Secondary areas in the food, beverage, pharmaceutical, and cosmetic industries
