- DC 13: 12 W, 125 V
Mounting and Pressure Connection
In environments with excessive vibrations, such as those found with fast-running engines, gears, and similar machinery, Danfoss recommends mounting the product on a heavy, solid base, like the engine frame. It is also strongly recommended to secure the inlet pressure tube to the same solid base to prevent vibrations of the inlet tube.
Connection Types:
- Thread
- Flange
Torque Recommendations:
- For the bellows and piston version, the recommended torque for the pressure connection is 4-5 Nm.
- For the diaphragm version, the recommended torque for the pressure connection is 1.5 ± 0.5 Nm.
- For electrical connections, a torque of 0.2 ± 0.1 Nm is recommended.
Operating Temperature
The operating temperature range for the bellows and piston version is -40 °C to 85 °C.
The operating temperature range for the diaphragm version is -10 °C to 85 °C.
Adjustment Screw
One full turn (360°) of the MBC setting screw is approximately equal to 7% of the full setting range.
