The valve has a spindle (18) cooperating with a valve body in a body and bearing a handle (2). A safety device is coupled with the spindle by operation of the handle for exchanging rotational torque. A sliding mating surface is assigned to a housing (16), and the handle is rotatably guided on the housing. A passage (34) is encompassed from the handle and provided at a distal extremity of a sliding surface (36). The sliding surface and/or the passage are formed by a collet (26) that surrounds the housing. A gap is formed among a handling head (4), the spindle and/or a mold part. |
