Ball valves are bi-directional, they could handle the flow in both directions.

To install a ball valve correctly:

  1. Make sure that the pipes are well aligne;
  2. Place the fixing tool in the part of the valve which is closer to the pipe;
  3. Do not exceed in using sealing materials such as (PTFE or other material), use it only on the thread.
  4. In presence of impurities in the fluid (such as limestone, dust or sand) install a strainer (see our items 411-412-411CM-412CM) to avoid damages to the ball and the seals.

Place the unfixing tool in the part of the valve which is closer to the pipe. Relief the pressure in the pipeline by opening the valve and allow the fluid to come out; unscrew the connections from the valve.

It is important to verify the valves periodically to make sure that the valve is in good working conditions. The valve is supplied at opening position.
The opening and the closing are made by a 90° rotation of the handle. In the opening position, the handle is along the body of the valve, while in the closing position the handle is across the body. The ball valve is an interception valve and not a regulation one, therefore it must be completely opened or closed; if left at an intermediate position, seals could be damaged.
Only if you have to empty the pipe system, to prevent from frost problems, the valve must be opened at an intermediate position (45°) up to the complete discharge of the liquid, after that the valve could be fully opened.
It is suggested not to use the valve for liquids with abrasive suspensions.
