The reversible valve includes a first valve connected to the fluid circuit.
A valve body having an inlet/outlet and a second inlet/outlet on the circumferential surface, a pair of pistons fitted inside the valve body so as to be able to slide freely in the axial direction while maintaining sealing properties, and an integrated valve between these pistons. and a seat that opens and closes a flow path between the first inlet and outlet and the second inlet and outlet, the pilot valve is connected to a high pressure side circuit and a low pressure side circuit, and is connected to a valve of the reversible valve. having a first inlet and a second inlet and outlet, each connected to the outside of the pair of pistons at both ends of the main body;
A reversible solenoid valve device comprising a four-way valve that selectively connects these inlets and outlets to the high-pressure side circuit and the low-pressure side circuit.
