Product Description

MAIN CHARACTERISTICS : These valves are powered by an electric motor and be in two different operating depending on whether the motor is charged (fig.2) or not (fig.1) . An auxiliary switch can be installed on request and activated when the valve is switched .Valves are equipped with an external lever for manual positioning of the shut-off ball in a central position (fig. 4).They also have a built -in by-pass to balance the hydraulic circuit when the valve is closed.

OPERTING: Fig. 3A shows the valve deactivated and flow form outlet C returns, through the by - pass into path B which is the return heating system. The by-pass passage diameter is small In addition, causes load loss p that can be measured using chart. The lode loss that is generated is for compensation and is equivalent to the header and the radiators. Fig. 3B shows the valve when it is activated. Outlet C-D is open and the fluid returns path A-B, which is the return form the heating system. Note: Do not install the valve upside down, with the cover facing down as it is a possible receptacle of water or condensation

USING THE MANUAL LEVER: A lever is placed on the side of the servomotor that permits manual position of the shut off ball in an intermediate position (fig.40). This is useful when emptying and refilling the pipeline system. The manual lever is automatically reset whenever the valve is activated by electricity.

AUXILIARY SWITCHES: All versions can be equipped with a single-pole micro switch (M1 version with C-NO connection )or a two -pole micro switch (M1S version ). There is a special kit for installing single-pole auxiliary switch even in versions that do not come factory - equipped with this switch (M1 Kit) The M1S kit cannot be installed in versions, which do not mount them originally.
