Ball Valve is a valve or valve with a round disc-shaped flow controller (like a ball / hemisphere). The ball has a hole, which is in the middle so that when the hole is in a straight line or in line with the two ends of the valve / valve, the flow will occur. Ball valve is widely used because of its ease of repair and ability to withstand high pressure and temperature. Depending on what material they are made, the Bal Valve can withstand pressures of up to 10,000 Psi and temperatures around 200 degrees Celsius.
