Overview
DV type throttle valves and DRV type one-way throttle valves are flow control valves for simple and precise speed regulation of actuators. They function as shut-off valves when fully closed.
The colored scale marks on the knob indicate the flow adjustment magnitude. A larger opening of the colored triangle corresponds to a higher flow rate. In addition, the valve can be reset to the originally set adjustment position according to the scale during re-adjustment.
