摘要： A valve apparatus for use in the removal of shuttering by means of compressed air or other gas. The apparatus comprises a valve body insertible into an aperture in a shuttering plate and having a flange formed at one end thereof for abutment with the inside surface of the shuttering plate. The valve body has a hollow cylindrical portion which extends from the flange and is externally screw-threaded to engage a nut which can be screwed towards the flange so as to clamp the shuttering plate between the nut and the flange, thereby securing the valve apparatus in position. The cylindrical body portion is also connectible with a pipe for supplying compressed air or other gas and accommodates a valve closure device which normally closes an opening through the flange end of the valve body. The valve closure device preferably has a frusto-conical closure element which seats in said opening, the opening also having a frusto-conical configuration but the angle of taper of the closure element being greater than that of the opening, the maximum diameters of the closure element and opening being substantially equal.
