Altitude valve one-way flow (elevated tank fill)

Product Overview
Closes when the water tank level reaches desired level. Opens when head of the water level became lower than the inertia of the altitude pilot (variable between 0,3 up to 0,8 mwh) and depending by the pilot range. The valve shall control the filling of a reservoir to an adjustable water level. The altitude pilot is located on the main valve at the bottom of the reservoir. The pilot is connected with a properly pipe with the reservoir level with a sensing line (the
sensing line isn’t included). This valve is used instead the float controlled valve where is requested a not intrusive control pilot. The valve installation in many cases is simplified if compared with the float pilot valve. The on-off function means reservoir supplied by pumping station – fire protection tank – with intermittent working.

Additional features
– Pressure sustaining-minimal inlet pressure;
– Solenoid on-off control function. A remote control switch on / off the valve position;
– Check function. When the outlet became higher than inlet the function prevent the back-flow;
– Flow rate limiter control;
– Pressure relief or maximum inlet pressure surge control;
– Two ways flow (tank fill discharge);
– Delayed opening control from 1 up to 10 mwh.
