Ball valves are a reliable way to control the flow of liquids or gases in a system. Whether you're dealing with a plumbing setup at home or a more complex industrial application, knowing how to open one properly can prevent damage and ensure smooth operation.

Step 1: Check the Handle Position

Before doing anything, take a look at the handle. If it's perpendicular to the pipe, the valve is closed. If it's in line with the pipe, it's already open.

Step 2: Turn the Handle

To open the valve, rotate the handle a quarter turn (90 degrees) so that it lines up with the pipe. This movement shifts the internal ball, allowing fluid to pass through freely.

Step 3: Open with Care

If the valve has been unused for a while, open it slowly to avoid sudden pressure surges that could damage the system. A gradual turn helps prevent water hammer or pressure shocks.

Step 4: Check for Proper Operation

Once the valve is open, observe the system. Ensure there are no leaks, unusual noises, or resistance in flow. If anything seems off, consider closing the valve and investigating further.

A Few Tips to Keep in Mind

• Don’t force it: If the handle feels stuck, forcing it can cause damage. It might need lubrication or maintenance.
• Know the system pressure: If the valve is part of a high-pressure system, be extra cautious when opening it.

• Regular maintenance helps: Keeping the valve clean and well-maintained ensures it opens and closes smoothly over time.
