1/2" BSP Quick-Acting Float Valve for Water Tanks

Hydraulic water level regulator designed to replace conventional ballcock valves in tanks and cisterns.

This float valve transitions instantly from fully open to fully closed, eliminating repeated pump stop-start cycling during tank filling. The high flow rate enables rapid tank replenishment with minimal pressure loss, whilst the delayed re-start feature (approximately 3 cm water drop) further reduces pump cycling frequency. An adjustable arm extends up to 60 mm across six settings.
