<br>※Refer to the manifold exploded view in the catalog for the part numbers for additional valve stations.
Refer to the following for the SY series manifold blanking plate assembly model: <br><br>

<br>Note) Consider using a VEX1□3□ series precision regulator for tension control or pressing control.
<br>Note 1) When port 2 (A) is retaining vacuum, there may be a decrease in vacuum power due to leakage from the vacuum pad and piping. Continue vacuuming at the vacuum suction position. <br>Note 2) This product cannot be used for emergency shut-off valves.
<br>Note 1) Air consumption is approx. 9.5 L/min (ANR) [at a supply pressure of 1.0 MPa]. <br>Note 2) If there is an abnormal amount of air leakage from the PE port, the diaphragm may be damaged.
<br>Note 1) The vacuum source for the VHK2 is piped to the 2 (A) side. <br>Note 2) Valve leakage is allowed for the VHK series.
<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>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>Since more than 40 years have elapsed since production began, and they are scheduled to be discontinued, they are no longer listed in the web catalog.<br>If replacing a valve, we recommend switching to one of SMC’s current products from the SY or VFR series in consideration of future availability.
