What it is

The motorised 2-port valve is a Glow-worm control component used on Clearly Solar and SS storage cylinder installations. It opens and closes the flow path through the circuit under the control of the appliance's heating and hot water demand signals. The valve is supplied under Glow-worm part number 0020010158.

Signs this part needs replacing

  • The valve does not open or close when the appliance calls for heat or hot water
  • The actuator motor runs continuously, buzzes or fails to move the valve spindle
  • Hot water or heating remains stuck on when there is no demand
  • Water weeps from the valve body or spindle gland
  • The valve lever moves freely with no resistance, indicating a failed internal mechanism

Before you order

  • Confirm your appliance model against the fit list above
  • Check the existing valve is a 2-port type and note its wiring and pipe connections before removal
  • Have the Glow-worm part number 0020010158 to hand when ordering
