The Altitude Valve controls the high water level in reservoirs.
The Suzhou Walter Flow Control Equipment Co.,Ltd. Model A010 Altitude Valvecontrols the high water level in reservoirswithout the need for floats or otherdevices. It remains fully open until the shut-off level is reached. This valve is designed for one-way flow only.
This valve is hydraulically operated and pilot controlled. The pilot control operates on the differential in forces between a spring load and the water level in the reservoir. The desired high water level is set by adjusting the spring force.
The pilot control measures the reservoir head through a customer supplied sensing line connected directly to the reservoir.
The spring of pilot is according to the height of shut-off level.
