Electro-pneumatic proportional valve:

Flow type (VEF) Controls the flow rate step-less according to current. (It is a 2/3 port valve that has an electrical throttle valve function.) A model that is suitable for operating conditions, such as the number of ports or maximum effective area, can be selected.
