A compound valve device comprises a body member, a first valve member being located in the body member and controlling the fluid communication between a first input port and a first output port, and a second valve member being located in the body member and controlling the fluid communication between a second input port and a second output port. The two valve members operate in sequence, without a significant difference in time in response to one signal pressure.
