Detailed Description The features of the embodiments described in this disclosure, as well as the various exemplary embodiments, may be combined with each other ("mixed and matched") unless specifically stated otherwise. Urostomy devices are typically used to collect urine from a urostomy that connects the urinary system (urine system) in the body with the surface of the abdomen of the user. The appliance is directly or indirectly attached to the skin around the user's urethral stoma. The urostomy appliance comprises a collection pouch for collecting urine. The pouch is typically provided with an outlet that includes a valve at its bottom to allow the user to drain urine to a suitable location, such as a toilet, during the day. At night, a conduit for the collection bag may be connected to the valve. However, there is still a need for a more convenient solution for the user. Embodiments relate to a valve for discharging fluid from a urostomy pouch, wherein the valve comprises a first valve part comprising a head part, a handle, an inlet, a first bore, at least one outlet opening and a distal closure, and a second valve part comprising a cannula, a second bore and a valve outlet, the first bore and the second bore forming a channel for transporting fluid from the inlet to the valve outlet, the cannula surrounding the handle and being adapted to close the channel for preventing fluid discharge, the distal closure of the first valve part being adapted to close the valve outlet of the second valve part, wherein the valve comprises one or more arms extending between the distal end and the proximal end, the one or more arms having a distal end connected to the cannula and a proximal end coupled to the head part, wherein the one or more arms are arranged at a distance from the cannula to form a gap between the one or more arms and the cannula, wherein the one or more arms are adapted to move into the gap towards the cannula such that the cannula is displaced away from the head part of the first valve part and to open the channel and simultaneously allow fluid to be discharged through the distal end of the valve into the second closure. The valve as described above has the advantage of facilitating the user to discharge its urostomy pouch for fluid. The user may simply press or squeeze one or more arms to open the valve outlet. As the one or more arms move toward the sleeve into the gap, the sleeve moves away from the head portion of the valve and the distal closure member simultaneously moves into the second aperture so that the passageway allows fluid to drain through the valve. During valve opening, the user does not need to reposition both hands. Thus, the valve is easy to use and the user controls the flow of fluid through the valve. In addition, the valve operates to avoid any unwanted dripping or spilling. Typically, the valve may be a urostomy valve, such as a urostomy pouch valve. Whenever reference is made to the proximal end of the valve, the reference is to the end closest to the urostomy collection pouch. Also, whenever reference is made to the distal end of the valve, the reference is to the end furthest from the collection pouch. The axial direction, the longitudinal direction and a central longitudinal axis (L) of the valve extend from the inlet to the valve outlet. The radial direction is transverse to the axial direction. The central longitudinal axis (L) (as shown in fig. 2) is an axial axis passing through the center of the valve in the longitudinal direction. The collection pouch of the urostomy appliance generally comprises a front wall on the distal side and a rear wall on the proximal side. The walls are made of a gas and liqui
