Valve Body: The main part of a ball valve is the valve body that contains all of the internal components for on/off control. Rotary Ball: A ball with a center hole through which the media flows is the main characteristic of ball valves that differentiate these valves from other valve types. The hole of the ball through one axis connects the inlet to the outlet.

Also known as proportional V-ball valves, these have a motor that adjusts and regulates flow in applications with higher flow rates and pressures than solenoid valves. As you increase the intensity of the electrical signal, the motor opens the valve, moving a ball with a V-cut opening that proportionately allows more flow as the valve opens. They're often integrated into PLC …

Both valves are installed with their shafts facing upstream to ensure double-positive isolation. The differential pressure supports the first valve's tightness. Unlike ball valves, the higher the cavity pressure is between the two TOVs, the more support is provided to the second valve seating, even in the remote case of torque application failure.
