1. A manifold-type valve assembly capable of being changed-over between a single-type valve and a double-type valve, comprising:

  • one solenoid-actuated valve or two solenoid-actuated valves to constitute the single-type valve or the double-type valve, the single-type valve and the double-type valve being actuated by one and two solenoids, respectively; and

    manifold blocks for accommodating the solenoid-actuated valves thereon individually, while connecting the solenoid-actuated valves to other ones mounted on neighboring manifold blocks, each manifold block having a power supply apparatus, wherein the power supply apparatus includes;

    a power supply terminal, for providing an electrical power to drive the solenoid-actuated valves of the single-type valve and the double-type valve;

    a circuit board connected to the power supply terminal and having a first surface and a second surface, the first surface having a single-type valve circuit for the single-type valve and the second surface having a double-type valve circuit for the double-type valve; and

    a male connector and a female connector installed at opposite sides of the circuit board and connected to their neighboring female connector and male connector in neighboring manifold blocks, respectively,wherein each of the single- and the double-type valve circuit has valve contacts arranged in two rows, the valve contacts in a first row being connected to the valve contacts in a second row with offset by the number of solenoids and, for each valve circuit, the offset contact in the second row being connected to the power supply terminal; and

    wherein each of the male connector and the female connector has connector contacts corresponding to the valve contacts in each valve circuit.
