Page 2: Purpose And Scope
This document describes the installation, operation and maintenance instructions for CMO Valves’ AB series knife gate valves. AB series knife gate valves are designed to handle various liquids with up to 4% suspended solids, con- trolling their fl ow, isolation and passage in pipelines within the specifi ed pressure and temperature range; if used for gravity discharge of dry solids, it is recommended to install the valve with the body arrow pointing opposite to fl... -
Page 3: Transport And Handling
• To prevent damage, especially to the anticorrosive protection, it is recommended to use soft straps or belts when lifting CMO valves knife gate valves. These straps must be fi tted around the top of body. • If the equipment is packed in wooden boxes, these must be provided with clearly marked holding areas where the slings will be placed when securing them. - Page 4 KNIFE GATE VALVE - AB KNIFE GATE VALVE - AB SERIES SERIES ADVANTAGE ASPECTS TO BE CONSIDERED DURING ASSEMBLY Before installation, inspect the valve body and components for any damage during transport or storage. Make sure the valve body’s inside cavities are clean. Inspect the pipes and the fl...

When the union to the conduit is screwed it has to be placed a watertight seal between the conduit and guillotine to avoid possible leaks to the exterior.
- Page 6 Position number 1: Prefered and recommended orientation. Fig. 4 Position number 8: The valve can be installed in this position, although contacting CMO Valves is recommended in such cases. Positions 2, 3, 6 and 7: For large valves (over DN300), the maximum angle permitted with the installation vertical is 30°.
- Page 7 (electrical connections, pneumatic connections, instruments, etc.). All valves from CMO valves are tested and verifi ed at our facilities, although the packing gland nuts may come loose during handling and transport and need to be retightened.
- Page 8 PNEUMATIC ACTUATOR (double and single acting) CMO Valves pneumatic drives are designed to connect to a 6-bar pneumatic grid, although these units can withstand up to 10 bars. The pressurised air used for the pneumatic drive must be correctly fi ltered and lubricated. Correctly identify the equipment’s pneumatic connection ports/inlets, and use fi...

Manipulating or modifying the multi-way valve is forbidden unless expressly authorised by CMO Valves. - Page 10 KNIFE GATE VALVE - AB KNIFE GATE VALVE - AB SERIES SERIES IMPORTANT SAFETY ASPECTS • To work under suitable safety conditions, the magnetic and electrical elements must be at rest and the air tanks depressurized. Likewise, also the electrical control cabinets must be out of service. The maintenance personnel must be aware of the safety regulations and only work can be started under the order of the on-site safety personnel.
