Ball Valves

In this type of valve, a rotating ball at its centre, known as a rotary ball, regulates the flow of liquids, vapours and gases. This ball has a hole, known as a bore, at its centre, and a shaft fixed on top of it. The bore is responsible for controlling the passage of substances, while the shaft may be turned using manual or automated levers to open and close the valve. Ball valves are typically compact, affordable and easy to handle. Premium-quality ball valves are also highly durable and resistant to high pressure, volume, and temperatures. Many modern home appliances – including washing machines, dishwashers – as well as specific industries like oil and gas, pharmaceuticals, food and beverage, and automotives make use of ball valves in their equipment.

Brosco’s ball valves are sturdy and durable, ensuring that equipment leveraging these valves can adequately regulate the flow of substances.

2 PC/3 PC Ball Valve Flange End

If a fluid gets contaminated while flowing in its channel, backflow of this fluid can contaminate its source. For this reason, backflow of fluids should be prevented to avoid contamination.

Check valves manufactured by Brosco prevent backflow successfully and are resistant to high pressure and temperatures.

Forging 3PC Bolted Design

In this process, a press, hammer or die is used to hammer and roll the metallic ball valve into its shape. Basically, heated metal is shaped into the required design so that the ball valve can fulfil its intended purpose.
