2.5 Vacuum- overpressure safety valve with tracing band
For cold environments it is possible to install tracing ribbon around the vacuum- overpressure safety valve to prevent it
from freezing. Although the safety valve is designed to withstand a certain level of frost, the additional tracing ribbon is an
optional feature that is advisable for environments with long periods of frost.
