Do balance valves require less force to open compared to conventional globe valves?

Balance valves are designed to provide precise flow control and are typically engineered to open and close with less mechanical effort than conventional globe valves. This reduced force is due to their internal design, which includes features such as a balanced plug that minimizes the pressure differential across the valve when in operation.

In contrast, conventional globe valves often necessitate more effort to open because their design involves overcoming a greater resistance due to the shape of the seating surface and the flow characteristics. The geometry in a globe valve can create higher friction and requires more torque to operate.

Thus, stating that balance valves require less force to operate reflects their purpose in providing easier and more controlled flow management, making them advantageous in systems where precise flow regulation is important.
