A handle () for valves () comprising a connecting region () for connecting the handle () to a spindle () of the valve (), an actuating arm () for actuating the valve (), a locking lever () arranged resiliently in the actuating arm () for engaging the actuating arm () and a locking and guide disc () for locking and guiding the handle (), the locking and guide disc () having a greater external diameter than the connecting region () and being arranged to be able to be connected to a flange region () of the valve ().

Handle for valves

A handle () as actuating device for valves () is proposed, comprising a fastening head () for fastening to a spindle () of the valve () and an actuating arm () for rotatably actuating the spindle, the spindle () being arranged in a valve housing () so as to be rotatable about the axis of rotation of a sealing part, the actuating arm () being arranged to be movable perpendicularly to the axis of the spindle () from a closed position into an open position of the valve (). The actuating arm () has means () for preventing the actuation of the handle (), the fastening head () has a fastening means () for fastening the handle () to the valve spindle (), and the handle () has a sealing plate () for sealing the fastening means ().

A valve arrangement with at least two connecting regions and with an actuating device is proposed, the valve body having a lead-through region for guiding a spindle and a receiving housing which encloses at least the lead-through region of the valve body being provided for receiving the means for sensing the valve position. The receiving housing, which can be easily adapted to the respective field of use, can be integrated in a simple manner in existing valve arrangements and the compact and flexible arrangement of the means for sensing the valve position in the receiving housing ensures to an increased extent that the valve position will be correctly indicated.

Valve arrangement

A ball valve is provided with a one-piece housing, in which a ball is accommodated such that it can rotate. In addition to an upper bearing point, the ball valve has a lower bearing point, which is located diametrically opposite the first. The ball and the housing are matched to each other in such a way that the ball can be inserted into the housing from the outside via a fluid opening. In order to fix the ball inserted into the housing, provision is made for screw-in elements which have a spherical seal on the front side.
