<br>③ Manifolds with kits other than the serial transmission kit (“S”), which includes options “F,” “L,” “M,” “P,” and “T,” do not have common polarity. Therefore, it is acceptable to mount either VQC1000/2000 positive common or negative common valves. However, it is not possible to mix them. The wiring also depends on the common polarity of the valves.
<br>② For the standard type, the part number is “VHK2A-02S-06F.” In July 2019, the VHK series was refreshed as the VHK-A series. The knob is now equipped with a function to prevent the knob from coming out, but the specifications and dimensions are the same as those of the existing product. Refer to the catalog for the different 1 (P) and 2 (A) combinations.
<br>Note 1) There is no external pilot type VFS1000 or VFR6000 series valve.<br>Note 2) Although there is an external pilot type VFR4000/5000 series 3-position valve, it cannot be used in this way because the P port needs to be pressurized.
