Identification & Selection of FAR Rubinetterie S.p.A. Valves and Genuine Spare Parts

Italian manufacturer FAR Rubinetterie S.p.A.

(founded in 1974 in Gozzano, Province of Novara, Italy; operating 4 manufacturing plants in Gozzano and San Maurizio d’Opaglio spanning over 18 700 sq.m, producing and testing approximately 30 000 units per day under UNI EN ISO 9001, UNI EN ISO 14001, and ISO 45001 quality systems) specializes in

brass shut-off, balancing, and safety valves for hydronic heating, plumbing, air conditioning, and solar thermal installations.

For rapid and accurate selection of complete valves or replacement maintenance kits, specify the 4-digit base series code cast onto the valve body or listed in your engineering schedule (such as manifold 3850, underfloor group 3462, pressure reducer 2815, replacement cartridge 2890, self-cleaning

filter 3947, strainer mesh 3942, H-block 1425, thermostatic mixer 3950, or actuator 1919), main thread size (from 3/8 to 2 inches), and branch outlet geometry (M24x19 metric thread, 3/4 inch Eurokonus, or 1/2 inch flat seat).

From a photograph of the installed valve body, pressure gauge, or handwheel, our engineers verify the exact factory modification code, alloy finish (CB753S/CW617N yellow brass, nickel-plated, or chrome-plated brass), and select matching compression adapters for copper, multilayer, or PEX tubing in

14–32 mm diameters.

MultiFAR Manifolds (3850, 3825, 3500) & Underfloor Heating Manifold Groups (3462, 3477)

MultiFAR distribution and balancing manifolds (series 3850, 3825, 3500, 3911, 3467) provide individual branch isolation and flow balancing in radial domestic water and radiator heating networks at operating pressures up to 10 bar and fluid temperatures up to 110 °C.

Modular sections with 2, 3, and 4 outlets and 3/4 or 1 inch trunk bores thread together without liquid sealants thanks to integrated EPDM O-ring face seals, forming headers up to 12 circuits.

MultiFAR 3850 and 3825 balancing manifolds feature a non-rising handwheel stem mechanism equipped with an integrated mechanical memory stop scale, preserving exact hydraulic balancing positions when a circuit is closed and reopened.

Dual-sided identification disks snap into the handwheels to label each plumbing branch.

For low-temperature radiant underfloor heating, we supply pre-assembled manifold groups 3462 and 3477 (from 2 to 12 loops) equipped with 0.5–5 l/min flowmeters, thermostatic return valves for 1919/1909/1929 electrothermal actuators (230 V or 24 V), automatic air vents 2050, 0–80 °C thermometers, and

CombiFAR / TermoFAR mixing stations.

Water Pressure Reducers (2815, 2825, 2878) & Self-Cleaning Strainer Filters (39A7, 3947)

FAR diaphragm and piston pressure reducing valves of series 2815, 2825, 2878, and 2850 (connection sizes from 1/2 to 2 inches) safeguard indoor plumbing systems and industrial equipment against water hammer and elevated municipal mains pressure (up to 25 bar inlet rating, or 16 bar on compact

bodies), maintaining stable downstream pressure between 1 and 6 bar at temperatures up to 75 °C. An internal pressure-compensation chamber prevents inlet pressure swings from affecting the set outlet pressure.

All moving regulation components are housed inside a single unitized replacement cartridge (model 2890): during routine servicing or diaphragm wear, the cartridge is extracted from the top without unthreading the brass body from the pipeline.

For closed-loop heating system make-up lines, series 2106 automatic filling units (0.5–5 bar setting) integrate a pressure reducer, check valve, and shut-off cock.

Self-cleaning mechanical water filters of series 39A7 and 39M5 (featuring a 360° rotatable connection flange and neodymium magnet) and inline models 3947, 3940, and 3935 (with 1 or 2 pressure gauges, rated up to 25 bar and 95 °C) utilize replaceable AISI 304 stainless steel mesh cartridges (model

3942) in 100 µm or 300 µm filtration grades with bottom backwash ball valves.

TermoFAR Thermostatic Mixers (3950, 3955), Radiator Valves & Boiler Pump Groups (2168)

TermoFAR thermostatic mixing valves (models 3950, 3955) and high-temperature SolarFAR valves for solar thermal collectors (model 3953, inlet temperature up to 110 °C) blend hot and cold water streams to maintain mixed outlet temperatures within 30–65 °C at pressures up to 10 bar.

Built-in Anti-scald thermal safety immediately shuts off hot water inflow if cold water supply is interrupted.

In radiator control applications, FAR manufactures thermostatic and manual valves 0267NO and 1610, the Monostile architectural chrome series, thermostatic heads 1824 and 1828, and bottom-connection H-blocks 1425 and 1428 with 50 mm center spacing and 360° swivel elbow ports for one-pipe and two-pipe

radiator circuits (rated up to 10 bar and 100 °C).

For boiler room headers and hydronic distribution, we supply full-bore ball valves 3079 MC and TOPFAR (up to 40 bar and 150 °C), 2-way and 3-way motorized zone ball valves (230 V and 24 V, 40 s rotation cycle), dirt separators 2275/2260, pre-insulated boiler pump groups 2168 (125 mm center spacing),

and multi-profile PressFAR 5511 press fittings (TH, H, U profiles for 14–32 mm pipes).
