HYDRAULIC FEATURES The "HAMMER STOP" device has been designed in order to attenuate the "water hammer" phenomenon which is created in a closed conduct when there is a abrupt variation of the fluid speed. This phenomenon presents itself when there is quick sequence of pressure excesses and drops which creates instability and generates noise and which can provoke serious damages to the systems and the connected devices. The water hammer damper must be installed near to the devices which can trigger this event such as ball valves, solenoid valves, mixing valves and all hydraulic components capable of stopping the water flow in the pipelines in a sudden way. The norm UNI 9182 "Installations for the alimentation and distribution of cold and hot water. Criteria regarding design, tests and management" recommends the use of a water hammer damper.

Before operating handles, please check the elimination pipeline which joining the relief valve guaranteed that the hot water from relief valve discharge the proper place, otherwise it may cause the bodily injure. If the handle is lifted, without water flowing out, it proves that the relief valve is invalid. Then it should turn off the water heater and ask pipeline personnel check and repair

HYDRAULIC FEATURES This automatic air vent valve is a single float valve designed for solar thermal energy plants, and carries out two main functions: the evacuation of a consistent air flow through the system (e.g. during loading/pressurization of the plant), and degassing which discharges air trapped in the pipeline, while functioning, in particular in the solar collectors. This valve has a paramount importance in solar thermal energy plants, evacuating and discharging trapped air in the pipelines and in the solar collectors. As a matter of fact, the presence of oxygen in the system can provoke numerous negative phenomena such as anodic corrosion, localized noise, air pockets, obstructions, etc., which may significantly compromise the performance and integrity of the systems. These valves are usually installed at the summit of the primary circuit in a solar thermal energy plant, and are resistant to the high temperatures that the heat-transfer fluids can reach, even in stagnation phases. Their suitability for application in solar thermal energy plants conforms to EN 12976 and EN 12977.     TECHNICAL FEATURES   Pressure :     Maximum allowable pressure (PN)   10 bar Minimum sealing pressure   0.2 bar (Grade A according to EN 12266-1) Range of operation air evacuation   from 0.5 bar to 5 bar (tolerance ± 10% max. detected) Temperature :     Maximum allowable working temperature (TS)   180° C (200° C in brief periods) Compatible fluids :     Glycolate solutions (glycol)   water and fluids Group 2 Heat transfer fluids in compliance with Italian national standards (UNI 8065 § 6)   Generic Fluids   50% Threading:     Pipeline connection   Threads according to ISO 228/1 Requirements and tests as per :     EN 1074-4 DESIGN Body and Plug in brass   EN 12165 - CW617N Seat and internal mechanisms   Brass - EN 12164 - CW614N Gaskets and o-ring   FLUORINATED RUBBER (VITON - FPM) Spring and counterweight   STAINLESS STEEL EN 10088-14310 (AISI 302) Nickel plating ELECTRODEPOSITED COATING EN 12540 (Cu/Ni5s)

The "ROMA" model automatic air vent is an automatic valve with single float, used for the evacuation and discharge of large volumes of air from water supply pipes. The integrated tap device is equipped with a dual position 90° male seal. Position "A" communicates the system with the upper air discharge recess while position "B" bypasses the system discharge recess and permits its draining through the front slot. This renders it particularly ideal for installation in zones outside buildings where there is a high risk of freezing. The "ROMA" air vent valve may only be installed vertically. In order to maximize the efficiency of the discharge, it should be installed at the highest points in the system or, if this is not possible, a TEE fitting should be installed at the input, as in figure "C". When installing it at the top of an ascension pipe, a conveyable discharge hose can be installed (option available only on request). The particular spherical profile of the internal floater-obturator in special thermoplastic rubber forestalls water spatter during the sealing phase, in closure. The absence of sliding guides, hence drag, allows the spherical floater an elevated velocity and precision in closing besides avoiding dangerous incrustations. At the discharge outlet there is a protective catch for dust and lint, which, over time, could deposit upon the opening of the cap, obstructing it; moreover, being perforated, anti-tampering seals may be used in compliance with legislation currently in force.The lower anti-spray guard allows the hydraulic thrust to be distributed evenly across the entire surface of the sphere, limiting the turbulence to a minimum and guaranteeing a highly precise closure. The "ROMA" model air vent is used in conditioning plants, sanitary installations for water distribution destined for human consumption outside buildings under EN 805, and irrigation plants. Maintenance of the "ROMA" model air vent consists in the periodic verification of the closure of the integrated stop device. The male obturator can be checked by tightening the front hexagonal nut while moving the lever from position "A" to position "B" and vice versa. The lever should only be actioned manually and not with the help of any tools. In the event of water outflow from the upper seat of the air vent, substitute the internal sphere-obturator, which is easily accessible by dismounting the body cap. In case of prolonged inactivity, the device should be disinfected according to EN 805 §12. This product adheres to the standards set forth by the international health authorities for the transport of alimentary fluids and potable water.

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 : Rated supply voltage 230 Vac.

MATERIALS : Valve body: Brass Valve cover: Brass Ball - bearing pin Brass Return Springs Stainless steel Motor cover Self - extinguishing ABS 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.
