整弁。It is equipped with a piston-shaped main valve, a pilot piping switching device with a flow rate detection paddle on the upstream side of the main valve, and two pilot valves with different set pressures.
Each of the following sides is connected to and cut off from the working chamber of the main valve, which is always connected to the upstream side, via the switching valve of the pilot piping switching device, and the secondary side of each of the pilot valves is The pilot piping switching device is operated according to the flow rate, which communicates with the downstream side of the main valve and flows through the main valve, and controls the opening and closing of the main valve by operating one of the two pilot valves.
