BELIMO
the R4..D series are specially designed
for high differential pressures and
temperatures up to 130°C. All mediacontacting
parts are made of food
grade materials. They are ideal for a
wide range of applications from district
heating substations to drinking or
domestic water and low temperature
steam. The motorised versions fitted
with our very fast running actuators
are also capable of handling many
challenging control tasks such as
domestic water applications. The NRFD
actuators with an emergency control
function (5 Nm, 230 V, 3-point), which
close the valve automatically in case
of a fault, are yet another exciting
innovation. They combine lower costs
with maximum protection in district
heating transfer stations
