The Hydraulic Valve is an automatic urinal flush control valve. The valve uses a simple patented mechanism which prevents water waste by ensuring that the auto-flush cistern is only filled, and can only flush, when the washroom is used.
Cistermiser Low Pressure Automatic Urinal Flush Control Valve
The Cistermiser Hydraulic Valve is installed on the supply pipe to the urinal cistern
The valve is activated by short-term pressure drops created by use of taps or WCs on the same supply
The valve is normally closed; when it is activated it opens and water passes to the urinal cistern until the pressures on both sides of the valve are equalised
When the cistern is full, the auto-siphon will flush
For use with tank fed systems with 3 to 5m head
Operating sensitivity: 20%
