4.Working Principle When air is supplied to either IN port, it is output from the OUT port. If the supply pressures are different from each other, the higher pressure is output to the OUT side. This product can also be used when the pressures are the same. When no pressure is applied to both IN ports, reverse flow from the OUT port can also be performed. - Page 10 Revision history Renewal. 2023.12 4-14-1, Sotokanda, Chiyoda-ku, Tokyo 101-0021 JAPAN Tel: + 81 3 5207 8249 Fax: +81 3 5298 5362 URL https://www.smcworld.com Note: Specifications are subject to change without prior notice and any obligation on the part of the manufacturer. ©...
