| RAW SERICE TERMOSTATIC MIXING VALVES |
| MAIN CHARACTERISTICS AND USES : The RAW thermostatic mixing valves are used in hot water systems for sanitary use. They keep the temperature of the mixed water supplied to the user constant even when the condition listed below it
The RAW thermostatic valves have a temperature range that is ideal for heating a centralized water system with heater. |
| OPERATION :The valves were designed to supply domestic hot water at an adjustable and constant temperature where no other regulating system is present. The very sensitive thermostatic element is positioned centrally inside the outgoing stream union and it guides a regulating shutter which adjusts the incoming cold water flow (C fig.2) to the hot water flow (H fig.2) according to the mixed water temperature (MIX fig.2) . The knob can be used to regulate the temperature of the outgoing water. There Is also a hot water locking system in case the supply of cold water is stopped (anti- scald system) |

| MOTORIZED 3-WAY ZONE VALVES WITH RETURN SPRING FOR HYDRAULIC CIRCUITS SERIES SF |
| MAIN CHARACTERISTICS : These are powered by an electric motor and can assume two operating positions depending on whether the motor is activated or not. One or two auxiliary switches can be installed on request. These are activated when the valve switches. The Valves are equipped with an external lever for manually positioning the shut-off ball in its central positing. |
| FUNCTION: Without electric power supply, the valve is positioned as shown in flig.1: Port A closed Port B open. The ball valve closes port a thanks to the elastic force exercised by the return springs. When it is powered, the servomotor overcomes the spring force and moves the ball form port A to B in about 20 Seconds and keeps it in that position until the electric power supply is shut off. When the electric power supply is shut off the return spring brings the shut-off ball back to port A. |
| USING THE MANUAL LEVER: A lever is located on the side of the motor. This is used to position the shut-off ball in an intermediate positing (fig. 3). This is helpful when filling or emptying the heating system. The lever reset, form manual to automatic, takes- place automatically whenever the valve is electrically by activated. |
FUNCTIONAL CHARACTERISTICS :
|
| AUXILIARY SWITCHES: A single pole micro switches (version M1), a two-pole micro switch (M1S version ) or two micro switches (M2 or M2 S version ) can be mounted on all versions.There is a special kit for mounting the single-pole auxiliary micro switch even in versions that do not carry it as an original part (M1 Kit.) .Kits M1S, M2 S cannot be installed in versions which do not mount them originally. |
MATERIALS :
|
| APPLICATION EXAMPLES 1 AS three -WAY ZONE VALVE The zone room thermostat controls opening and closure of the respective SF valves. When there is no demand it shut off power to the valve, which closes the zone and recalculates water back to the boiler return? Installing a meter as shown in the diagram permits efficient sub-division of operating costs. The load loss of the recirculation pipeline should be balanced to avoid excess flow rate variation in other circuit during valve operation. Note:Do not install the valve upside down, with the valve cover below the valve body, as it is a potential container for eventual leaks or water condensation. |
| APPLICATION EXAMPLE GIVING PRIORITY TO THE HOT WATER HEATER We use this installation system mainly on combined boilers to permit the temperature of domestic hot water to be adjusted at the desired valve. The valve is used for priority over the heating system. |

A Ball Valve is a valve that is opened by turning a handle attached to a ball inside the valve. It has a hole, or port, in the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you "see" the valve's position.
