However, if the pressure in port 2 is higher than port 1, the valve will not be able to block the fluid and it will flow from port 2 to port 1. Direct Operated 2 Port Solenoid Valve Series VX21/22/23 For Air Single Unit Symbol Note) Weight of grommet type. Add 10 g for conduit type, 30 g for DIN terminal type, 60 g for conduit terminal type respectively. �� Refer to “Glossary of Terms” on page 35 for details on the maximum operating pressure differential.
