upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure. it either opens or shuts in response to a remote pressure command. typical applications ■ computerized irrigation systems ■ drip-tape systems ■ low set pressure applications...
be pressurized to power the valve open. the main benefits of the double chambered valve are: full-powered opening & closing decreased pressure loss (no spring) non-slam closing characteristic isolated and protected diaphragm the model basic valve uses valve differential pressure to power the actuator...
