Many standard valve are often found to be unsuitable for slurry applications. However, some standard valve can be utilised successfully in installations for non-abrasive slurry. Valves for abrasive slurry must be selected carefully and a detailed knowledge of the slurry properties is essential. Valve manufacturers adopt different design principles for their products and similar valves from different manufacturers can be significantly different. The diameter of the valve flow port may be considerably smaller than the nominal pipe size suggests. Valve selection can only be successful when accurate information is available.
