What is the purpose of using a Special In-Line Gate Valve during hose service testing?

• A. To Prevent Injury From Hose Failure
• B. To Regulate Water Flow
• C. To Facilitate Hose Recoil
• D. To Measure Test Pressure

Answer: (A)

Safety and rapid isolation during high-pressure hose testing. A Special In-Line Gate Valve is used to quickly shut off the flow and isolate the test section if something goes wrong, preventing a high-energy spray that could injure nearby personnel. It provides a reliable, immediate means to stop the test without disconnecting equipment, which is essential when hoses are under pressure. This function is why it’s preferred here. The device isn’t meant for fine flow control, measuring pressure, or aiding hose recoil—those roles are served by other tools and components.
