PURPOSE:To obtain the valve capable of being operated by power and/or manually by a method wherein a power driving shaft and a valve body rotating shaft are separated and a manual handle is mounted to the valve body rotating shaft while the rotation is transmitted through the play of 90 deg. between the driving shaft and the rotating shaft. CONSTITUTION:A motor 4 is arranged at the upper part of the driving part 1 and the rotation thereof is transmitted to the driving shaft through a gear box 5 and a last stage gear 6, arranged at the lower part of the motor. The manual handle 15 is screwed into the threaded part 12a of a joint case 12 while the tip end 15a of the manual handle 15 is projected into the joint case 12. A joint member 14 in the joint case 12 is formed with a sector hole 14a, having an opening angle of 90 degree generally, and the tip end 15a is engaged movably within the sector hole 14a. |
