|3/4/5 Port Solenoid Valves

For VFS or VFR series 2-position valves, can either the A or B port be plugged in order to use it as a 2-port or 3-port valve?

Yes, this is possible. However, if using the product for air blow, the SUP port air pressure will drop. Select the external pilot type. (Refer to the FAQ about switching failure, which can be found here.)
For normally closed use: Plug the B port and pipe to the A port.
For normally open use: Plug the A port and pipe to the B port.
Note) Do not plug the exhaust ports (EA or EB); instead, mount a silencer. (The same goes for the PE port.)
