摘要： A valve without position indicating switches. Positions of the valve are detected from current magnitude measurements and current profile analytics. The current profile may be learned initially and relearned and adapted at each operation. The valve may be opened and closed by a driver that is actuated byan electrical current to control the opening and closing of the valve. The current may be regulated by a controller to open and close the valve appropriately.

摘要： A frictionless rotary valve comprising: a valve body to be connected within a gas meter, the valve body comprising: a seal, fixedly attached near an outlet of the valve body; and a valve disc, having a ball bearing attached to the valve body; and a gear mechanism comprising: a worm wheel engaged with a worm, wherein the worm wheel is attached to a second end of the valve disc; a drive gear connected to the worm, wherein a rotation of the drive gear in a clockwise direction rotates the worm wheel in an anti-clockwise and moves the valve disc in a closed position; a worm wheel stop, for restricting a movement of the worm wheel in the anti-clockwise direction and driving the worm wheel in a vertically upward direction; and a linear guide attached to the worm wheel.
