Description

DCL-02B can be used to drive valve or swinging arm with full range angle that is no more than 90 degree. The motor is automatically stopped by internal cams striking limit switches. Two more passive contact auxiliary limit switches are added to confirm valve position. Very compact size with unique design, the last stage drive with worm gear to insure self-locking.
