Starway - Worm Screw for Commex Motor Valve 1" (L = 140 mm) - 7039419

Starway – Worm Screw for Commex Motor Valve 1″ (L = 140 mm)

This is the genuine replacement worm screw for the Starway Commex motorized backwash valve in the 1-inch size variant. Measuring 140 mm in length, it is the drive component within the valve’s electric actuator, transmitting rotational force to cycle the valve between filtration and backwash positions. It is an essential spare part to restore precise, reliable operation of your Starway automatic backwash system.

Compatibilidade

This worm screw is designed specifically for the Starway Commex motorized valve in the 1-inch configuration with a 140 mm connection pitch. The Starway is a motorized 5-way valve used to automate the backwashing of pool sand filters. Always verify your valve’s size and connection pitch against these specifications before ordering — this part is not interchangeable with other size variants.

Porque o Genuíno Importa

The worm screw is a precision-machined internal drive component; an incorrectly dimensioned or poor-quality replacement can cause the actuator to slip, strip, or fail to reach end-of-travel positions correctly. Using a genuine Starway part ensures exact dimensional fit, correct material grade, and full compatibility with the Commex actuator’s torque rating — keeping your automated backwash cycle accurate and protecting the wider valve assembly.

Instalação

Replacement of internal actuator components such as this worm screw requires disassembly of the motor unit and should be carried out by a qualified pool technician. Ensure the power supply is fully disconnected before starting work. Refer to the official Starway service documentation for your specific valve model to confirm the correct disassembly and reassembly procedure.
