TOP COVER FOR A SOFT THROTTLING VALVE BODY, SOFT THROTTLING VALVE AND METHOD FOR ASSEMBLING A SOFT THROTTLING VALVE

The present invention relates to a top cover (5) for a soft throttling valve body (2), the top cover (5) comprising one or more fluid conduits for transferring a pilot fluid flow for setting a degreeof 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 thesoft 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 objectis 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. 本发明涉及一种用于软节流阀体(2)的顶盖(5)，该顶盖(5)包括一个或多个流体导管，
