F: The pulling force of the solenoid when a specified amperage is applied to the solenoid, or the force that is created by the pilot pressure. F: The force that is ceated by the port pressure (PA) that passes through the feedback passage and acts on the spool surface, and the spring force. OFF state F < F condition: See figure q. ON state Immediately after turning on F > F: See figure e. AR to 9 VEX ARX0 VY T AP00 (P) (R) Thereafter F = F: See figure w. Inw, port (R) is half open.

4 Series 000/V000 Current Pressure Characteristics The horizontal axis of the characteristics represents the output amperage of the power amplifier. (If NULL and GAIN are in the shipping condition, 0 to A can be viewed by substituting them with command signals 0 to V.) Outlet pressure (MPa) Outlet pressure (MPa) Current A Current A Selecting Electro-pneumatic Proportional Valve The response behavior of an electro-pneumatic is affected by the load capacity. Therefore, select an electro-pneumatic in accordance with the bore and the stroke of the cylinder to be used. (The diagram below is provided as a guide.) Cylinder stroke (st/mm) Unapplicable area Applicable area Bore size (ømm) How to Use DIN Terminal Wiring Applicable area Wiring procedure. Loosen the retaining screw and pull out the connector from the pin plug.. Make sure to remove the retaining screw, insert the tip of a flat head screwdriver into the groove below the terminal block and pry it up to separate the terminal cover from the terminal block.. Securely connect the wires to the specified terminals in accordance with the wiring procedure. Pin plug shape Terminal block Connection is not used for terminal and. Note) Coil has no polarity. Applicable cable (Cabtire cable) 0.7 mm,. mm / core, core (O.D. ø6.8 to ø.) based on JIS C and C. Outlet changing procedure To change the wire outlet, first separate the terminal cover from the terminal block. Then, reinstall the terminal cover in the desired direction (in 90 increments). How to Find the Flow Rate Air temperature of 0 C Subsonic flow at P <.89 (P + 0.0) Q = 6S P (P + 0.0) Sonic flow of P (P + 0.0) Q = S (P + 0.0) Q: Air flow rate [l/min (ANR)] S: Effective area [mm ] P: Amount of pressure drop P P [MPa] P: Upstream pressure [MPa] P: Downstream pressure [MPa] Note) Correction for varying air temperatures: Square the coefficient indicated in the table below with the flow rate that has been obtained from the above formula. Air temp. ( C) Coef. for compensation Precautions Be sure to read before handling. Refer to front matters and for Safety Precautions and pages 87 to 9 for Precautions on every series. Caution. Air supply Poor quality air could increase the spool s sliding resistance, while preventing it from attaining its specified characteristics. Use compressor oil with a minimal generation of oxidants and install a mist separator (SMC s AM series). Refer to pages and. Avoid using ultra-dry air since it may reduce the amount of lubricant and shorten the service life.. Mounting Vibrations are transmitted to the valve by the proportional solenoid s dither. If it is necessary to prevent the transmission of vibrations, insert vibration isolating rubber material. Thoroughly flush the pipe to completely eliminate any dust or scales from the pipe inside. Install a silencer (AN series) on the exhaust port. Be careful with the molded coil because it generates heat while current is applied to it.. Lubrication This product can be used without lubrication. But if lubricated, use turbin oil Class, ISO VG (with no additive). It is impossible to use spindle oil, machine oil, or grease.. Manual operation To check the operation of the valve without applying a current, remove the lock nut and use a screwdriver or the like to press the tip of the core. After checking the operation, reinstall the rubber cap in its original position. 706 Courtesy of Steven Engineering, Inc.-0 Ryan Way, South San Francisco, CA Main Office: (60) Outside Local Area: (800)

7 Port Electro-Pneumatic Proportional Valve Related Products: A solenoid valve for actuating a cylinder and an electro-pneumatic for pressure control have been integrated into a single unit. High response has been achieved. The size and the direction of the pipe port can be selected. The size of the electro-pneumatic proportion can be selected. Solenoid valves for actuating a stage stroke gun cylinder or a clamp cylinder can be mounted on an integrated manifold (maximum of 8 stations).
