The VCF_X4L and VCF_X4R valves are designed for fan coils with single coil, inserted in 4-pipe systems with "Hot" and "Cold" circuits fully
separated. The kits consist of 2 insulated 3-way valves and 4 connections complete with electro-thermal actuators, valve insulating cover-
ing and relative hydraulic fittings. The valves are an "all-or-nothing" type, typically closed.
