These single-seated valves are used for modulating control of hot/chilled water or steam in heating, ventilating and air conditioning systems. They are designed especially for use in high differential pressure applications (e.g. district heating) The valves can be operated by linear actuators series ML64... and ML74... In combination with dedicated actuators the DF...B...NI-SV safety linear valves are approved according DIN EN 14597 and marked with CE0035 e.g. for district heating application.
