Beschreibung
Zusammenfassung:	The present invention relates to a top cover (5) for soft throttling valve body (2), the top cover (5) comprising one or more fluid conduits for transferring a pilot fluid flow for setting a degree of opening of a main valve situated in a soft throttling valve body to the soft throttling valve body. Furthermore, the invention relates to a soft throttling valve (1) and a method for assembling the soft throttling valve (1). The object of the invention is to allow a good control of the pilot fluid flow while protecting the soft throttling valve body from damage due to valve failure. The object is solved by having a follower arrangement arranged to throttle the pilot fluid flow depending on the degree of opening of the main valve, further having a manual opening arrangement for manually opening the main valve and/or by further preventing a step-wise opening of the main valve in less than two opening steps. A method for assembling a soft throttling valve is also disclosed.
