<br>In such cases, the valves can be purchased as single units.<br>If the manifold base is of the special wiring specification “-K,” it is necessary to check whether the blanking plate position is single wiring or double wiring. Check the manifold specifications sheet of the SQ valve in use.
<br>One of the benefits of using 3-port valves is that they take up half the number of stations.<br>Common applications include the control of single acting air operated valves and the driving of single acting air cylinders.
<br>Note) For the single type, pressing the direct manual override switches the valve, and releasing it returns the valve to its origin position.
<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.
<br>When replacing an old VQZ series valve for maintenance, order a new VQZ series valve with a plug connector with a lead wire and wire the lead wire (there is no polarity even in for DC).
<br>If a substitute is selected based on the flow characteristics and port size, an SY7000 or VF3000 series valve will be suggested, but they differ in specifications and dimensions.<br>Select a model and part number according to the operating conditions. (e.g., For the VP4125-021G-X52: SY7120-1G-02, VF3130-1G1-02, VF3130K-1G1-02, etc.)
<br>Refer to the web catalog for the full part numbers to order a new VM series valve. (The VM/VZM/VFM series catalog can be found here.)<br>Note) There are also old valves with only “VM15” and “VM25” indicated on the product label. Refer to the new VM series catalog for the full part numbers.

<br>For details, refer to the "Min. allowable stroke length for auto switch mounting" in the catalog.<br>About the horizontal lines in the stroke table
<br>Note 1) For CDU/CDUK single acting spring extend type cylinders, the body dimensions of bore sizes ø20 and larger will extend beyond the standard dimensions.<br>Note 2) For CDUJ series cylinders, the body dimensions of bore sizes ø6 and larger will extend beyond the standard dimensions. The CU series catalog can be found here.
<br><br>The current part number for the old CDQ2B32-30D is “CDQ2B32-30DZ.” For this product, the auto switch mounting rail on the body has been changed to a round auto switch mounting groove. Cylinder body mounting is possible. A mounting bracket may be required if the auto switch in use is to be used as is. Check the auto switch model first.
<br>The operating pressure of JC series joints is 1 MPa or less, while JA series joints can accommodate up to hydraulic cylinders with an operating pressure of 3.5 MPa or less. JC series joints are also lighter than those of the JA series due to their aluminum case.
<br>Use a circuit in which both sides of the piston are balanced by a regulator with a backflow function to prevent cylinder lurching when restarting after a lock stop or when the manual lock is released.
