Valve, use of such valve, separator comprising such valve and method of cleaning a separator body

The present disclosure provides a valve (123), comprising a channel body (1231) defining a bent channel space, an elastically flexible membrane (1233), which separates a control space (Sc) from a flow space (Sf) in the channel space, a control connection (1232), providing a fluid connection to the control space (Sc), The control space (Sc) is provided at a radially outermost portion (Co) of the channel space, as per a channel bending radius (Ro), such that the membrane (1233) is flexible between an open position, whereby a cross section of the flow space (Sf) is substantially that of the channel, and a closed position, whereby the membrane substantially seals against a radially innermost portion (Ci) of the channel, as per the channel bending radius (Ri). Use of the valve in a separator is disclosed, as well as a separator comprising such valve and a method of cleaning a separator body.
