What is the purpose of small bypass valves around large gate valves?

• A. To measure flow rate
• B. To balance pressure on both sides
• C. To control fluid temperature
• D. To prevent sediment buildup

Answer: (B)

The purpose of small bypass valves around large gate valves is to balance pressure on both sides of the gate valve. When a gate valve is closed, significant pressure differentials can occur on either side due to flow restriction. This pressure imbalance can lead to difficulties in opening or closing the valve and might even cause damage or stress to the piping system. By having a bypass valve, a small amount of fluid can continuously flow around the gate valve, equalizing the pressure on both sides. This not only helps in maintaining the integrity of the valve and the piping system but also allows for more efficient operation when the gate valve needs to be manipulated. Implementing this design enhances reliability and longevity of the valves and overall system functionality.
