Overview The valve is available to mount in either horizontal or vertical flanged pipework. Ensure that the valve is mounted in the correct orientation so that the bottle hangs vertically down below the valve. The valve is able to sample both hot and hazardous media, so it is very important that suitable protective clothing and eye protection is worn when commissioning and operating the valve. Storage The sampling valve should be ideally stored in cool dry conditions in a dust free environment. The flange faces have serrated grooves and should be protected from damage. It is recommended that the valve should be left in its original packaging until ready for assembling in to the pipeline. Installation The valve is of a wafer style designed to be mounted in line between flanges. Choose a position within the pipeline that is easily accessible to ensure trouble-free function of the valve by the operator. The mating flange faces must be free from debris and foreign matter prior to installation. Any remaining gasket material should be removed from the flange faces. Gaskets Gaskets must be used when bolting up the valve within the pipeline. CRP Flex-Rite recommend Goretex GR expanded PTFE type gaskets or PTFE envelope gaskets. Bolting Materials Shoul
