1 1/4" BSP Quick-Acting Float Valve for Water Tanks

Instant shut-off float valve designed to regulate water levels in tanks and cisterns whilst eliminating pump cycle chatter.

This hydraulic water level regulator switches instantly from full flow to complete closure, preventing repeated pump start/stop cycling during tank filling. The high flow rate enables rapid tank refilling with minimal pressure drop. A delayed restart feature (approximately 3 cm hysteresis) further reduces pump cycling frequency when water is drawn from the tank.
