Valves in ER version
Valve in this version, without connected power supply of the solenoid, is in the closed position (Fig. 1c
and 2c item 1). By turning the crank at the BELIMO actuator in the direction marked on the actuator,
we open the partition. After complete opening, when the crank is released, the spring wound on the
actuator shaft should automatically close the partition and keep it in this position. Similarly as in the
case of other versions, movement of the partition when opening and closing must be smooth, without
stops, binds, and excess resistance, and valve partition must adhere to ventilation seals at the entire
circumference.
