Heavy duty pressure controls Type MBC 5000 and MBC 5100

MBC pressure controls are used in industrial and marine applications where space and reliability are the most important features. MBC’s are compact pressure controls, designed according to our block design to survive in the harsh conditions known from machine rooms onboard ships among others. BC’s have high vibration resistance and MBC 5100 features all commonly marine approvals. The fixed, but low differential guarantees accurate monitoring of critical pressures. MBV test valves can be delivered as standard option for MBC.

Features

• Designed for use in severe industrial environments
• High vibration stability
• Part of the Danfoss block system, consisting of MBC pressure controls, MBS pressure transmitters and MBV test valves
• MBC 5100 with all major ship approvals
• High repeatability
• Optimal compact design for machine building purposes
• Intended for alarm indication, shut down, control and diagnostics in many applications – motors, gears, thrusters,
pumps, filters, compressors etc.

How to choose

To achieve the best operating conditions for MBC pressure controls, it is recommended to apply the following rules of thumb:

Choose:
• the MBC type/types which meet the demands for the operating pressure
• the MBC version with the lowest possible setting range
• a diaphragm type, if pressure peaks and pulsations occur in the system (if possible)
• bellows types, if low differential is needed
• piston type for high pressure
