Safety Instructions Caution SMC develops, designs, and manufactures products to be used for automatic control equipment, and provides them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not allowed. Products SMC manufactures and sells cannot be used for the purpose of transactions or certification specified in the Measurement Act of each country. - Page 5 Design Warning Cannot be used as an emergency shutoff valve etc. The valves presented in this catalog are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted.
- Page 6 Fluid properties Use a general compressed air with a filter of 5 μm or less mounted on the inlet of the piping. (Excluding dry air) Caution Leakage voltage Particularly when using a resistor in parallel with a switching element and using a C-R element (surge voltage suppressor) to protect the switching element, take note that leakage current will flow through the resistor, C-R element, etc., creating a possible danger that the valve may not turn off.
- Page 7 Caution 1. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Install piping so that it does not apply pulling, pressing, bending or other forces on the valve body.
- Page 8 Maintenance Warning Removing the product The valve becomes hot depending on the fluid temperature. Confirm that the valve temperature has dropped sufficiently before performing work. If touched inadvertently, there is a danger of being burned. (1) Shut off the fluid supply and release the fluid pressure in the system. (2) Shut off the power supply.

- Page 10 3. Outline This operation manual introduces L shape 2-port valve with high response and instantaneous mass flow rate controlling capacity which discharges air in acoustic velocity and bruches off dust on the back filter or blows out work by taking advantage of impact wave. Though main valve opens and closes by the pressure operation from the pressure working chamber, the opening velocity of the main valve is set as high velocity to gain maiximum efficiency with smaller air consumption.

VXF22,23A*** bonnet diaphragm Ass'y spring VXF24A*** hexagon head bolt (4 places) VXF25A*** Fig1. Bolt tightening procedure 1． Disassembly/ Assembly Procedure 1) Loosen hexagon socket head cap screw 1 so that bonnet 2, spring 3 and diaphragm Ass'y 4 are disassembled.
- Page 16 Note 1) Check visually that thread part of hexagon socket head cap screw is completely got through the bolt hole of diaphragm Ass'y at assembly. If thread is not properly screwed in the bolt hole at tightening, leakage or diaphragm damage might be caused. Screw-in thread part of hexagon socket head cap screw to the bonnet and diaphragm Ass'y before assembling them on the body so that the risk of diaphragm falling is minimized.
