What it is

The MZX4501 is a 1 inch, 3-port bronze seat valve for low pressure hot water (LPHW) systems, made by Schneider Electric under the Satchwell/TAC range. It requires a compatible Satchwell/TAC actuator to operate, sold separately.

Signs this part needs replacing

  • Valve fails to switch or sticks in one position
  • Leaking from the valve body or spindle
  • Actuator runs but the valve doesn't respond
  • Uneven heating or hot water output across the system

Before you order

  • Confirm the part number printed on your existing valve matches MZX4501
  • Check your actuator is compatible with the Satchwell/TAC MZX range
  • Isolate the system and drain down before removal
