The BSR safety block system is an automasm that,
when coupled to the J4C mul voltage electric
actuators, lets the valve situate in a preferable
posion NC or NO, when there is a power supply
failure. Inside of the housing there are a BSR print
circuit board and a baery pack, which is kept in
connuous charge.
In case of the valve is not in the preferable
posion and there is a power supply cut, the BSR
system returns the valve back to the preferable
posion by means of the baeries tension, operang
as a “single acng” actuator.
