The BSR safety block system is an automatism
that, when coupled to the J4C multi voltage electric
actuators, lets the valve situate in a preferable position
NC or NO, when there is a power supply failure. Inside
of the housing there are a BSR print circuit board and a
battery pack, which is kept in continuous charge
In case of the valve is not in the preferable position and
there is a power supply cut, the BSR system returns the
valve back to the preferable position by means of the
batteries tension, operating as a “single acting” actuator.
