How do I connect a K-Rain 7001 1"BSP Electric Sprinkler Valve to 240v mains?

The title asks the question, I'm stumped. The solenoid specs are 24v ac 0.43amps inrush and 0.25amps holding. What do I need to connect this unit to the 240v mains supply?

A 240 volt to 24 volt step down transformer. HVAC suppliers will have this part. Get one with at least 10.32 va rating, larger vA is better.

Thanks Snaps, much obliged but before I checked your reply I had already purchased the K-rain controller.
