Series VH Specific Product Precautions Be sure to read before handling. Refer to front matters 58 and 59 for Safety Instructions and pages to 7 for //5 Port Solenoid Valve Precautions. Warning Warning Design. ot suitable for use as a selector valve or a divider valve. The valve can malfunction due to air leakage.. ot suitable for negative pressure. The valve can malfunction due to air leakage.. Do not supply air pressure from other ports than (P) port. Air leakage may occur when the pressure is supplied from other ports. Selection. Intermediate stop When stopping the cylinder piston in the middle using the position closed center valve, it is not possible to stop it correctly and precisely as the hydraulic equipment due to the air compressibility. Do not use this valve because it has slight air leakage and can not hold a stopping position. When it is necessary to hold a stopping position, select an equipment to prevent displacement and design the circuit. Caution Warning Piping. Ensure connection so that air is supplied to the port (P) port. Air leakage may occur when the pressure is supplied from other ports.. ote that in the case of the option of different (P) porting position, porting indication on the body and flow direction by handle operation are reversed. Environment. When the valve is exposed to a large amount of dust, install a silencer into the port (R). When dust enters the valve from the port (R), it may cause air leakage. Caution. Use in low temperature environments The valve can be used at a temperature down to 5 C. Take appropriate measures to avoid freezing of drainage, moisture, etc.. Operation method The valve must be switched to each position instantly and securely. Stopping the handle halfway between the extreme positions may cause malfunction. 9
