DESCRIPTION
VCF45C / VCF47C are kits made up of an insulated 3-way valve with 4
connections, an electrothermal actuator and related fittings. They are
suitable for installation on VED-VED_I fan coils with both right and left
connections.These are three-way valves and 4 all or nothing type con-
nections, normally closed, with by-pass flow control fitted as a mixer
with G 3/4" Male flat fittings, powered at 230V ~50Hz The valves can be
controlled by the control panels (accessory) which are enabled for the
valve checking function. Consult the control panel characteristics before
selecting a panel. The VCF45C / VCF47C kits must be installed on the
main coil and are compatible with VED-VED_I sizes:
VCF45C: VED430, VED432, VED440, VED441, VED530, VED532,
VED540, VED541
VED530I, VED532I, VED540I, VED541I
VCF47C: VED630, VED632, VED640, VED641, VED730, VED732,
VED740, VED741
VED730I, VED732I, VED740I, VED741I
VCF45H / VCF47H are kits made up of a three-way valve with 4 con-
nections, an electrothermal actuator and related fittings. They are suit-
able for installation on VED-VED_I fan coils with both right and left
connections. These are three-way valves and 4 all or nothing type con-
nections, normally closed, with by-pass flow control fitted as a mixer
with G 3/4 "Male flat fittings, powered at 230V ~50Hz.The valves can
be controlled by the control panels (accessory) which are enabled for the
valve checking function. Consult the control panel characteristics before
selecting a panel. The VCF45H / VCF47H kits must be installed on the
secondary heating only coil and are compatible with VED-VED_I sizes:
VCF45H:VED432, VED441, VED532, VED541
VED532I, VED541I,
VCF47H:VED632, VED641, VED732, VED741
