No water hammer, but weak switch contact

        Comments about CTS-7524 3/4" 24 Volt Zone Valve:

        The valve works very well for heat control and water hammer. The Contact that is normaly off loses its contact force in about two years. After they get weak, when used with a Zone valve controller, the contacts supply enough voltage to turn the Activation lamp on but not enough current to close the relay used to activate the burner and Pump. You can get a few more months out of them by bending and cleaning the contacts. This is something that could easly be fixed with a better spring metal in the switch contacts.

              Other piping options should be considered, FNPT connections as an example.
              Price is too high for us to use on a regular basis, not comparable to Hwell, Invensys, Johnson
              Shipping took forever, PEX could not deliver quantity of 50 ordered, consider your stock levels or supplier ability to fill orders

                  With the power off the pin on the valve is extended. With the power on the pin is actuated closed, down and not extended.
                  Hope this helps.

                  Hi There,
                  The valve with the actuator on it, with no power is in the closed position
                  that is NC. You need power to open the valve.
                  If you take the actuator off of the valve, the valve will go open as it is
                  a spring operated valve assembly that is a spring at the bottom opens up
                  the valve. Make sure the system that the valve is in is shut off before
                  doing any maintenance on the valve.
                  Best regards,
                  Stan

                  It should be closed.

                  I have had 23 years of experience with these valves installed in 47
                  apartments. They work well and the heads are simple to replace, without
                  tools. When the power goes out, I believe the valve remains in its current
                  position with the control head still in place. Either open or closed
                  depending on where it was when power was lost. (not 100% sure that if the
                  head is open it wouldn't close with loss of power) However, if you lose
                  power, you simply pop the head off and the valve itself would fail in the
                  open position. The valve is spring loaded to be in the open position, if
                  there is no control head in place. The control head pushes down on a
                  plunger to close the valve and allows the plunger to rise when there is a
                  call for heat. Sorry I'm not 100% sure if a valve with the control head in
                  place would remain open if it was already open when power was lost. It has
                  never been an issue that I've had to address. But if you lose power you
                  can get heat, as long as your boiler and circulator are running, by popping
                  the head off. Also, if the control head stops working at some point, you
                  can pop it off to continue to get heat while you pick up a replacement.

                  It should be in the closed position...if it does not close when power is off. Try cleaning the contacts...This is a very old part and should be replaced with a newer up to date one. Hope this answered your ?
