|3/4/5 Port Solenoid Valves

What is the difference between VHK series 2-port valves and 3-port valves? Also, where is the VHK3 series valve’s exhaust port?

The shape and dimensions of 2-port valves and 3-port valves are the same. Appearance differences are as follows: the knob is gray for the standard 2-port valves and blue for the standard 3-port valves. There is no exhaust port that can be piped to on VHK3 series 3-port valves. The exhaust of the VHK3 travels through the flow passage in the center of the stem and is exhausted from the gap between the knob and the body. The VHK series catalog can be found here.
