Low Pressure Drop
The two piece of ball valve design allows material to flow straight through the valve, minimizing pressure drop across the valve. The two piece of ball valve also have higher flow coefficients (Cv) compared to other control valve types of a similar size; this means that a smaller two piece of ball valve can be used to achieve the same flow rates as a comparable control valve of a larger size.
Bubble Tight Shut-Off
The two piece of ball valve uses the “floating ball principle, which will provide a bubble tight shut-off in addition to the modulating flow control. When the valve is closed, upstream pressure pushes the ball against the downstream seat, thus enhancing the seal. These can control or shut off bi-directional flow, which proves to be especially beneficial in gas applications. Comparable control valves often require additional shut-off valves; two piece of ball valve eliminate the need for these additional valves, saving the user cost and reducing the number of overall components in the system.
Precise Flow Control
Precision machined two piece of ball valve are available with 60° and 90° V openings and offer equal percentage flow characteristics. As the ball rotates, desired flow rates can be achieved by positioning the ball anywhere between 0° and 90°. Response time is also increased due to the ability to use smaller actuators with these valves.
High Shut-Off Pressure
The two piece of ball valve feature a quarter turn (90°) ball rotation, allowing them to operate and shut off at much higher working pressures. Because of this, smaller lower torque actuators can be used, which results in cost savings and higher efficiency in the user’s application.
