    It might be that. The only thing you can do is try removing one of the two springs. I did that and it worked for me.

    If removing the spring doesn't work you will need to change the valve to a slower closing one {taco}.

    First thing...

    Check to see that the water is flowing in the direction of the arrow cast into the body, and that the valve isn't connected to a long, poorly supported piping run. Secondly, your pump may be oversized, and trying to push too much water thru the valve. Third, you can remove one of the springs for a "quick & dirty field fix", or convert the valve to the new 5000 zone valve series that closes slowly. For a 3/4, part number would be V8043E5012.

    zone valves

    if the zone valves are on the feed along side the pump your pump might be oversized. you could try to put the valves on the return or add a differential preasure bypass.

    There is

    one spring. Should I remove this spring? I posted pics of the zone valves.

    Well, if you are sure there is only one spring then probably somebody removed one allready...
