<br><br>Internal pilot type valves<br><br><br>With the solenoid’s electromagnetic force, a small pilot operated valve (direct operated 3-port valve) is switched, and the supply pressure is sent to the main valve, which switches the main valve.

<br>Mounting interchangeability:<br>Mounting screws, brackets, and manifolds for the underside of the valve have not been changed.<br>The main changes are as follows.<br>① The max. allowable operating pressure of old VT307 series valves is 0.9 MPa. While the max. allowable operating pressure of new VT307 series valves (standard) is 0.7 MPa.

<br>Refer to the “How to Order” section in the catalog.<br>The part numbers when replacing only the upper valves for use with the existing sub-plates (pipe section) are “VS4124-00□” and “VS4134-00□.”<br>A gasket and bolt are included. <br>Ex.)

<br>The VS3135 and VS3145 series catalogs can be found here.<br><br>The VS3135 and VS3145 series have been in production for more than 40 years.<br>There are no interchangeable current products, but the following models are listed for reference.

<br>For the VF2□00 series base mounted plug-in type: the VFS2□00 series (Note 1)<br>For the VF2□10 series base mounted non plug-in type: the VFS2□10 series (Note 1)<br>For the VF2□20 and VF2□30 series body ported type: the VFS1□20 and VFS1□30 series <br>*1) For the base mounted type, valves of the VFS2000 series can be mounted on old VF2000 series manifolds and sub-plates.

<br><br>When using or planning to use a cylinder with a solid state auto switch and ordering only the cylinder, suffix “-X1810” to the end of the part number.<br>Ex.) MY1B10G-300-X1810<br><br>For cylinders ordered with a solid state auto switch, the suffix “-X1810” does not need to be added. Just use the part number “MY1B10G-300-M9BW.”

<br>Note that a grease pack does not come with the seal kits. <br>Order the grease for the standard MGP series product using the part number “GR-S-010.” <br>Be sure to check the part number of the MGP-Z series product before ordering the seal kit. The old MGP series was discontinued in April 2012.

<br>Old product: <br>Rubber bumper: CG1N□-PS <br>Air cushion: CG1A□-PS<br>Refreshed product: <br>Rubber bumper & air cushion: CG1N□Z-PS (the number in the “□” indicates the cylinder I.D.) <br>Note 1) There is no seal kit part number for bore sizes ø50 and larger because the products cannot be disassembled by the customer.

<br>Refreshed MB and MB1 series products have a “Z” after the stroke in the part number. Keep in mind that no changes were made to the mounting dimensions. <br>The features of the MB-Z series can be found here. <br><br>The main changes made to refreshed MB□ series cylinders are as follows.

<br>6) Perform a suction test on the actual device to determine whether it can be used or not. <br>Note) This is the general procedure for selecting a vacuum pad, however, it does not apply to all types of vacuum pads.<br>Ultimately, testing using the actual device is the best way to determine whether a pad is ideal for the application.

<br><br>Note 2) “-X256” special order specification/with option “T” (with a terminal block for operating, error, and remote operation signals), remote control, and a terminal block for a stop switch<br>The special order part number suffix “-X256” can only be used for the IDF6E/IDU6E to 75E.

<br>When P1 (inlet pressure) becomes lower than P2 (outlet pressure), the check valve opens and the pressure in the diaphragm chamber is discharged to the P1 side.<br>This allows the outlet pressure to flow back rapidly to the inlet side due to the mechanism that opens the main valve.<br>The AR20K-B to AR60K-B and the AR20K-D to AR40K-D series are regulators with a backflow function.
