The air from P portmoves to needle valve u, where its flow is adjusted, and flows to port. The meter-in control of needle valve u slowly moves the cylinder from to. When / PP P after the cylinder reaches, piston t fully opens and P increases rapidly as shown from C to D and becomes the same pressure as PP. Initial Operation Return Stroke Pressure stroke Pressure time chart (Meter-out control) example PP P Cylinder movement with fixed orifice PR (tmospheric pressure) Time Since piston t holds the fully open condition, during normal operation the cylinder s speed will be controlled by the usual meter-out control.

The pressure difference generated at this time lets the check valve y open and the residual pressure on the port side is quickly exhausted from R port. PP (P) P () (R) 6

8 V000/000/000/000 Series Specific Product Precautions e sure to read this before handling the products. Refer to back page 0 for Safety Instructions and pages 87 to 9 for F.R.L. Precautions. on Design. ctuator drive When using solenoid valve or actuator in the outlet side of this product, implement appropriate measures to prevent potential danger caused by actuator operation.. Holding pressure Since the valve might have slight interal leakage, it is not suitable for holding pressure in a tank or another vessel for a long period of time.. Maintenance space llow the sufficient space for maintenance and inspection. Selection. Confirm the specifications. The products presented in this catalog are designed only for use in compressed air systems. Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to specifications.) Please contact SMC if using for other fluids than compressed air.. Extended periods of continuous energization Please contact SMC if valves will be continuously energized for extended periods of time.. Operation of closed center solenoid valves Even if this product is used for closed center solenoid valves or actuator with a load factor of more then 0%, jumping (stick-slip phenomenon) cannot be prevented.. Using a regulator in the outlet side When mounting a regulator in the outlet side ( port side), use a residual pressure relief regulator (RK to 0K) or a check type regulator. With a standard regulator (R0 to 60), the outlet side pressure may not be released when this valve is exhausted.. Operation of solenoid valves in the outlet side To operate solenoid valves mounted on this product s outlet side ( port side), first confirm that the outlet side s pressure (P) has increased to become equal to the inlet side s pressure (PP). 6. Operation The residual pressure release function of this product is for emergency use only; therefore, avoid the operation in the same manner as ordinary port valves. 7. Using a lubricator If mounting a lubricator, mount it on the inlet side (P port side), of this product. If mounted on the outlet side ( port side), back flow of oil will occur and may spurt out of the valve s R port. 8. Operation for air blowing This product cannot be operated for air blowing due to the mechanism that switches the main valve to be fully open after the outlet side s pressure increases to approximately / of the inlet side. Selection. Voltage leakage Particularly when using a C-R element (surge voltage suppressor) for protection of the switching element, use cation that leakage voltage will increase due to leakage current flowing through the C-R element, etc. Power supply C coil is 0% or less of rated voltage. DC coil is % or less of rated voltage.. Low temperature operation lthough the valve can be operated at temperature as low as 0 C, measures should be taken to avoid solidifying or freezing drainage and moisture, etc. Switching element OFF C R Leakage current Mounting. If air leakage increases or equipment does not operate properly, stop operation. fter mounting or maintenance, etc., connect the compressed air and power supplies, and perform appropriate function and leakage tests to confirm that the unit is mounted properly.. Operation manual Mount and operate the product after reading the manual carefully and understanding its contents. lso keep the manual in a place where it can be referred to as necessary.. Painting and coating s or specifications printed or labeled on a product should not be erased, removed or covered up. Furthermore, please contact SMC before painting the resin parts, as this may cause adverse effects depending on the solvent. djustment. To perform the initial speed adjustment of a outlet side actuator, supply air from this valve s inlet side and turn ON the pilot valve. Then, rotate the needle counterclockwise from the fully closed position. Leakage voltage Valve 68

Connection threads Rc / Rc /8 Rc / Rc / Rc Piping. Preparation before piping efore piping is connected, it should be thoroughly blown out by air (flushed) or washed to eliminate cutting chips, cutting oil, and other debris from the pipe inside.. Winding of sealant tape When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not enter the piping. lso, if sealant tape is used, leave. to thread ridges exposed at the end of the threads. Winding direction Expose approx. threads Sealant tape. Tighten threads with the proper tightening torque. When screwing fittings into valves, tighten with the torques given below. Tightening Torque when Piping Model V000 V000 Proper tightening torque (N m) to to 8 to 0 8 to 0 6 to 8. Piping to products When piping to products, avoid making an error of supply port, etc., by referring to the operation manuals.. F.R.L. module combination When connecting to a modular F.R.L. combinations (C0 to 60), select one of the spacers, which are included. (Refer to page 67 for details.) However, modular combinations with C0- are not possible. Furthermore, connect soft start-up valves to the outlet side of the F.R.L. combination. 6. Inlet side piping conditions The nominal size of the piping material s or equipment s bore should be equal to or larger than the soft start-up valve s port size. The composite effective area of the inlet side s (P port side s) piping or equipment should be equal to or larger than the values below. Composite effective area (mm ) 0 When the piping is restricted or the supply pressure is insufficient, the main valve will not switch and air leakage may occur from the R port.

Precautions. ir Supply. Use clean air. Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction.. Install air filters. Install air filters close to valves at their upstream side. filtration degree of µm or less should be selected.. Implement countermeasures by installing aftercooler or air dryer, or water separator, etc. The air including excess drain may result in a malfunction of v a l v e s a n d o t h e r p n e u m a t i c e q u i p m e n t. I m p l e m e n t countermeasures by installing after-cooler or air dryer, or water separator, etc. Operating Environment. Do not use valves in such environments where corrosive gases, chemicals, or brine or water or steam is airborne, or where valves can be directly exposed to any of those.. Do not use in an explosive environment.. Do not use in locations influenced by vibrations or impacts.. protective cover, etc., should be used to shield valves from direct sunlight.. Shield valves from radiated heat generated by nearby heat sources. 6. Take suitable protective measures in locations where there are contacts with water droplets, oil, or welding spatter, etc. 7. In a dusty environment or when valve switching noise is intrusive, install a silencer in the R port to prevent dust from entering, and to reduce noise. Maintenance. Perform maintenance and inspection as shown in the operation manual. If handled improperly, damage may occur in machine or equipment or an operational error may result in.. Equipment removal and supply/exhaust of compressed air When equipment is removed, first confirm that measures are implemented to prevent dropping of workpiece and runaway of equipment, etc. Then cut the supply pressure and power, and exhaust all compressed air from the system using its residual pressure release function.. Low frequency operation Valves should be switched at least once every 0 days to prevent malfunction. (Use caution regarding the air supply.). Manual override operation When the manual override is operated, connected equipment will be actuated. Confirm the safety before operating.. Drain removal Remove drain from air filters periodically.
