  • Hi.  Yes as long as both planes are within the limits (so any leaks do not run into the actuator).  You cannot reverse the actuator, but the lever if fine on the bottom.

  • I'm afraid not. The old style ones are obsolete.
  • I'm afraid you will need to drain your system to below the point of the motorised valve.
  • Yes it is. No, the complete valve needs to be swapped.
  • Yes it will
  • There should be around 45 degrees rotation.
  • I'm afraid not. You will need to change the valve body as well.
  • It is a direct replacement. You will need to drain the system.
