More recently, on the PEX plumbing and radiant heating networks as brass fittings water shutoff dominated by two products: "valve cork entrance omental tapered Threaded Brass Ball Valve BVT012D" and "Sweat Brass Ball Valve BVS012D". Passport service life of tube-omental valve - 8 years, the average life-at least 1500 cycles, time to failure - at least 400 cycles. In fact, these valves after 40-50 cycles begin to be capricious: cotton gland packing into a brown porridge, soaked in water, and the cone stop tube, originally friction to the body under the influence of abrasive solids and sludge sediment in the water begins to hang out in the body, passing water in the closed position.

If you also take into account the extremely high coefficient of local resistance plug valves , it is not surprising that plumbers often just throw the locking cap, leaving the body dubious backdrop of the pipeline.As sleeved valves, then the passport MTBF of 1,300 cycles, their actual performance is enough for 20-40 cycles, after which the sediment accumulated on the sealing saddle, do not allow completely block the flow by turning the valve itself in another "architectural extravagances." Moreover, the coefficient of local resistance they simply record - from 16 to 20. That is, at a flow rate of 1 m / sec, passing through the valve, the pressure of the liquid is reduced by 1 m of water.

With the advent of the market brass ball valves, they immediately appreciated was evaluated, and the demand for these products increases, as well as their scope. Now such products can be found in any economic stall. However, despite their apparent similarity, not all ball valves are really reliable and durable. Along with high-quality Italian taps, more and more pushed over in the trade cheap Polish, Chinese and Turkish valves, whose quality is far from perfect? In the struggle for the vast US market, some sellers have begun to distribute cheap "consumer goods" for branded products, quite simply to sell a fake, so I'd like to give some practical advice to buyers' brass ball valves.

As a rule, forgery in performance is much inferior to the original products. Their use in water and heating systems can lead to accidents and big material losses. Counterfeits can cause serious damage and human health.Wright Valves BVT034D recognized world leader in designing and manufacturing valves water Italy is known for such major firms as Matca-Norca, Wright Valves, Bugatti, Giacomini, RBM, Rastelli, Tiemme etc. Italian province of Brescia consists of a huge industrial zone, where the hangars is fittings under the brand name companies from Germany, Britain, USA, UAE and dozens of other countries. In practice, up to 70% of all ball valves entering the world market, made in Italy, where the business is engaged in more than 2000 companies. Stiff competition forces the firms to constantly improve its products and production technology. At the heart of high performance ball valves of the best world producers is the perfection of their design, precise adherence to the requirements of production technology and strict control of chemical composition of materials.
