Abstract
An isolation valve has a two-part housing defining a pair of coaxial tubular sections 11, 12 with a cylindrical section 14 located intermediate and transverse to the tubular sections 11, 12. The housing is clamped about a pipe 20, so that tubular sections 11, 12 sealingly engage the pipe 20 and the pipe 20 extends through the cylindrical section 14. A sleeve member 30 is slidable within the cylindrical section 14 and has a cutting formation 33 adjacent one end by which the section of pipe 20 extending through the cylindrical section 14 may be cut. The sleeve member 30 also has diametrical apertures 51 which can be aligned with the tubular sections of the housing 11, 12. A valve member can be located in the sleeve member 30 for selectively opening and closing the apertures 51. <IMAGE>
