Working conditions Pilot valve Pressure conditions Operation description Internal construction/Cylinder actuation circuit (Meter-out control) example Operation description of the soft start-up valve When the pilot valve © is energised or turned ON manually, the spool © is pushed down due to the pilot air and gets into contact with the valve ©, closing the flow passage to port 3 (R). At this time, force that pushes the valve © > force that pushes down the spool ©. Therefore, the flow passage from the valve © to port 2 (A) is still closed. Furthermore, the piston © is pushed down due to the...

AV2000-A/3000-A/4000-A/5000-A Series Speciﬁc Product Precautions 1 Be sure to read this before handling the products. Refer to the back cover for safety instructions. For F.R.L. precautions, refer to the “Handling Precautions for SMC Products” and the “Operation Manual” on the SMC website: http://www.smc.eu 2. Holding pressure Since the valve might have slight internal leakage, it is not suitable for holding pressure in a tank or another vessel for a long period of time. 3. Not suitable for use as an emergency shutoff valve etc. The valves listed in this catalogue are not designed for...
