MBC pressure switches are used in industrial and

marine applications where space and reliability

are the most important features.

MBCs are compact pressure switches, designed

according to our block design to survive in the

harsh conditions known from machine rooms

onboard ships.

MBCs have high vibration resistance and

MBC 5100 features all common marine approvals.

The xed, but low dierential guarantees

accurate monitoring of critical pressures.

MBV test valves can be delivered as standard

option for MBC.

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

Thread

Flange connection on MBV 5000 Test Valve

• A diaphragm type, if pressure peaks and

pulsations occur in the system (if possible)

• Bellows type, if low dierential is needed

• Piston type for high pressure

Mechanical connection

Adjustment

Not applicable for piston type
