摘要：
A valve comprises a valve housing (10),an annular valve seat (12) and a valve closure plate (14) having a deformable annular seal (52), the valve being operable from a first, closed condition in which the valve closure plate (14) engages the valve seat and into a second, open condition in which the valve closure plate (14) is displaced from the valve seat. The valve closure plate (14) comprises first (14a) and second (14b) portions which are releasably securable together to retain the deformable seal (52) on the valve closure plate and the second portion (14b) of the valve closure member is removable with the valve in the closed condition to allow removal and/or replacement of the deformable seal (52).
