1. Balancing (adjusting rod is installed inside the brass ball valve. To adjust the flow of stock to raise or lower until you reach the desired flow. The scale on the rod (without valve) shows the exposed configuration. Position adjustment rod relative to the passage of the ball does not depend on the position of the shut-off ball valve. Therefore, when closing / opening the ball valve flow adjustment does not change.)
2. Unlocking / locking of the flow (valve can be used as a shut-off ball valve. At the close / open the ball valve flow adjustment does not change.)
3. Draining the working environment (The valve can be used as a drain. For this reason the measuring input.)
4. Measuring the temperature and flow (flow can be measured by flow in l / s and m3 / h. To enter the measuring probe into the flow measuring input is used.)
Brass Ball valves – devices that closing some of which are made in the form of a sphere with a hole. In order to under the pressure of liquid or gaz ball valve does not deviate in the ball valve has a special groove. Brass Ball valves are widely used in pipeline, petrochemical and water industries. Ball valves have indisputable advantages. For example, they are more durable than the valves, lighter and more comfortable. Brass Ball valves can be manufactured from various metals such as brass ball valve or ball valve steel Our company offers a wide range of ball valves. You can buy a ball valve steel or brass ball valve of your choice.
Gate Valves and Brass ball valves find their application in many industries from chemical industry to the household, from the military to the food industry. These constructs are found everywhere from ordinary homes, to nuclear power plants. She works in various mediums: from water to a complex of toxic chemicals from gas to oil.
Relatively recently in-house plumbing and heating networks as a brass water valves dominated by two products: “Crane cork passing cone gland flange 11B6bk” and “valve flange 15B1p. Passport life tube-gland crane -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 act up: cotton gland packing into a brown porridge, soaked in water, and tapered tube stop, which was 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 we take into account the extremely high coefficient of local resistance plug valves (3,5-5,7), it is not surprising that plumbers often just throw the locking cap, leaving the body dubious decoration on the pipeline.
With regard to the coupling valves, then the rating mean time to decline. Brass ball valves 1300 cycles, their actual performance is enough for 20-40 cycles, after which the sediment accumulated on the sealing saddle, can not completely stop the flow by turning the valve itself in another “architectural extravagances” . In addition, the coefficient of local resistance to them just a record – from 16 to 20. That is, at a flow rate of 1 m / s, passing through the valve, fluid pressure is reduced by 1 m of water. column.
With the advent of the market brass ball valves for their dignity were immediately appreciated and the demand for these products increases, as well as their scope. Now, such products can be found in any hardware shop. However, despite their apparent similarity, not all ball valves are really reliable and durable. Along with high-quality Italian taps, more splash in the trade of cheap Polish, Chinese and Turkish cranes, whose quality is far from perfect. In the struggle for the vast USA market and some well-known manufacturers began to produce cheap “consumer goods”, so I’d like to give some practical advice to buyers brass ball valves.
