A Yoke usually has openings to allow access to the stuffing box, actuator links, etc.. Structurally, a Yoke must be strong enough to withstand forces, moments, and torque developed by the actuator.
A Yoke nut is an internally threaded nut and is placed in the top of a Yoke by which the stem passes.
In a Gate valve e.g., the Yoke nut is turned and the stem travels up or down. In the case of Globe valves, the nut is fixed and the stem is rotated through it.
Hand-operated valves are usually equipped with a handwheel attached to the valve’s stem or Yoke nut which is rotated clockwise or counter clockwise to close or open a valve.Globe and gate valves are opened and closed in this way.Hand-operated, quarter turn valves, such as Ball, Plug or Butterfly, has a lever for actuate the valve.
There are applications where it is not possible or desirable, to actuate the valve manually by handwheel or lever.
