WW750-80-X – Altitude Control Valve AS5081 , WaterMark
Tolerance between valve opening and closing standard is 1m
If greater than 1m differential is required, a second pilot can be added to give variable differential opening levels
Valve double chamber design for ultimate reliability under very low operating pressures
The Model 750-80-X Level Control Valve is a hydraulically controlled, diaphragm actuated control valve that shuts off at pre-set reservoir high level and fully opens in response to an approximately 1m level drop. Drops are sensed by the 3-Way altitude pilot mounted on the main valve. If required, a secondary pilot can be added to increase level greater than 1m. It is the first valve of its design in Australia to be compliant and certified for inclusion in municipal water supply and building services.
