ValveOperation

-

Manufacturer guidance

  • When the set point is pre-set to 57°C, the valve completely opens up to a valve temperature of 52°C.
  • Between 52°C and the set point of 57°C, the valve starts to close. When the set point temperature has been reached, a minimum volume flow is continuously flowing through the circulation system.
  • If the storage temperature is further increased to temperatures greater than 70°C to effect disinfection, the valve increases the flow.
