Performance (EN 60770)
Overload and burst pressure – without pulse-snubber (MBS 1200)
Overload and burst pressure – with integrated pulse-snubber (MBS 1250)
Application
Cavitation, liquid hammer and pressure peaks
may occur in liquid lled systems with changes
in ow velocity, e.g. fast closing of a valve
or pump starts and stops.
The problem may occur on the inlet and outlet
side, even at rather low operating pressures.
The media viscosity has only little eect on the
response time. Even at viscosities up to 100 cSt,
the response time will not exceed 4 ms.
* Only available with M12 × 1 1.5 P high pressure port, type FC06. Please contact Danfoss.
