Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC)*1) , and other safety regulations. - Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
- Page 5 Design Warning ！ 1. Extended periods of continuous energization -This product is the pulse operation type,so continuous energization can cause failure. 1.The pulse energization time (ON time) should be 300ms or less. 2. Not applicable as a explosion proof solenoid valve 3.
- Page 6 Installation Warning ！ 1. If air leakage increases or the equipment does not operate properly, stop operation. After installing, supply compressed aie or electricity to the product and perform appropriate functional inspections to check it is mounted properly. 2. Do not apply external force to the coil section. 3.
- Page 7 Wiring Caution ！ 1. Wire Use electric wires with a conduction area of 0.5 to 1.25mm for wiring. Make sure that no excessive force is applied to the wires. 2. Adopt an electric circuit without chattering at the contacts. 3. Keep the voltage within -10 to +10% of the rated voltage. The voltage drop is measured at the lead wire with the coil connected.
- Page 8 Operating Environment Caution ！ 1. Do not use in an atmosphere containing corrosive gases, chemicals, sea water, water, steam, or where there is direct contact with any of these. 2. Do not use in potentially explosive environments. 3. Do not mount the product in locations where it is exposed to radiant heat. 4.

Page 9: Operation Principle
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. - Page 10 5 .

Page 12: Disassembly / Assembly Procedure
7. Disassembly/ Assembly Procedure (Refer to page 13.) 7.1 For diaphragm assembly When disassembling, shut off the pressure source and release the residual pressure, then disassemble according to the following procedure. 7.1.1. Disassembly Procedure 1) Loosen hexagon socket head cap screw 1 so that bonnet 2, spring 3 and diaphragm Ass'y 4 are disassembled. - Page 13 4) Includes springs. 5) VXF26: If the customer ordered a product without a silencer and retrofitted the silencer, the operation at ON may become unstable. When retrofitting a silencer, it is necessary to replace the diaphragm assembly. Even if the silencer is removed from a product with a silencer, the diaphragm assembly must be replaced.
