| The "ROMA"model automatic air vent is an automatic valve with single float, usedfor the evacuation and discharge of large volumes of air from watersupply pipes. The integrated tap device is equipped with a dual position90 male seal. Position "A" communicates the system with the upper airdischarge recess while position "B" bypasses the system discharge recessand permits its draining through the front slot. This renders itparticularly ideal for installation in zones outside buildings wherethere is a high risk of freezing. The "ROMA" air vent valve may only beinstalled vertically. In order to maximize the efficiency of thedischarge, it should be installed at the highest points in the systemor, if this is not possible, a TEE fitting should be installed at theinput, as in figure "C". When installing it at the top of an ascensionpipe, a conveyable discharge hose can be installed (option availableonly on request). The particular spherical profile of the internalfloater-obturator in special thermoplastic rubber forestalls waterspatter during the sealing phase, in closure. The absence of slidingguides, hence drag, allows the spherical floater an elevated velocityand precision in closing besides avoiding dangerous incrustations. Atthe discharge outlet there is a protective catch for dust and lint, which, over time, could deposit upon the opening of the cap, obstructingit; moreover, being perforated, anti-tampering seals may be used incompliance with legislation currently in force. | The loweranti-spray guard allows the hydraulic thrust to be distributed evenlyacross the entire surface of the sphere, limiting | | TECHNICAL FEATURES | | Pressure : | | | | Maximum allowable working pressure (PN) | | 16 bar | | minimum accumulation | | 0.5 bar (Grade A according to EN 12266-1) | | Range of operation air evacuation | | from 0.5 bar to 16 bar (tolerance 10% max. detected) | | Temperature : | | | | maximum working temperature (TS) | | 0 C(excluding ice) +110C | | minimum plant storage | | -20 C (with recess fluid discharged) | | Threading: | | | | Pipeline connection | | Threads according to ISO 228/1 | | Requirements and tests as per: | | | | Air vents | | EN 1074-4 | | Seat tightness | | EN 1074-4 5.2.2 | | Stop device | | EN 1074-2 | | Pressure tightness | | EN 1982 B.7 | | Pressure resistance | | EN 1074-4 5.1.1 | | DESIGN | | Cast brass body and male | | EN 1982 - CB753SEN 1074-4 | | Cap in brass | | EN 12165 - CW617N | | O-ring | | NBR RUBBER | | Spherical floater | | THERMOPLASTIC ELASTOMER | | Sphere guard | | ACETAL RESIN (POM) | | | PRODUCT SIZE | | 20 - M - 3/4" | | 25 - M - 1" | | 33 - M - 1" 1/4 | |
