Page 2: Installation
• To prevent damage, especially to the anticorrosive protection, it is recom- mended to use soft straps to lift the CMO valves. These straps must be fitted around the top of body. •... - Page 3 KNIFE GATE VALVE - SERIE UB Before installation, inspect the valve to ensure no damage has occurred during transport or storage. Make sure that the inside of the valve body and, in particular, the seal area are clean. Inspect the installation’s pipes and the flanges to make sure they are clean.
- Page 4 KNIFE GATE VALVE - SERIE UB ASSEMBLY POSITIONS (horizontal pipe) In horizontal pipes it is recommended that CMO valves be assembled in vertical position, although other assembly positions are also possible. Position number 1: This is the most advisable position.
- Page 5 (electrical connections, pneumatic connections, instruments, etc). All CMO valves are tested on site, although it is possible that the stuffing box screws (in valves from DN50 to DN600) or the packing nuts (in valves over DN600) may come loose during handling and need to be retightened.

KNIFE GATE VALVE - SERIE UB fig. 6 Handwheel Lever Pneumatic chain actuator Geared Electric- Hydraulic Handwheel handwheel motor actuator actuator MAINTENANCE CMO will not be liable if the valves suffer any damage due to improper handling or without proper authorisation. The valves must not be modified except under express authorisation from CMO. - Page 7 KNIFE GATE VALVE - SERIE UB IMPORTANT SAFETY ASPECTS • In order to work under ideal safety conditions, the magnetic and electrical elements must be in idle mode and the air tanks depressurised. The electrical control cabinets must also be out of service. The maintenance staff must be up to date with the safety regulations and work can only start under orders from the site’s safety staff.
- Page 8 KNIFE GATE VALVE - SERIE UB REPLACING THE GLAND As mentioned above, valves DN50 to DN600 have a stuffing box seal rather than a gasket. Valves over DN600 do have the traditional gasket system. • REPLACING THE STUFFING BOX SEAL (VALVES DN50 - DN600) Make sure there is absolutely no pressure and fluid in the facility.
- Page 9 KNIFE GATE VALVE - SERIE UB MAINTAINING THE PNEUMATIC ACTUATOR The pneumatic cylinders in our valves are manufactured and assembled at our premises. The maintenance of these cylinders is simple, if you need to replace any elements or have any questions please consult CMO. Below is an exploded diagram of the pneumatic actuator and a list of the cylinder’s components.
- Page 10 KNIFE GATE VALVE - SERIE UB STORAGE To ensure the valve is in optimum conditions of use after long periods of storage, it should be stored in a well-ventilated place at temperatures below 30ºC. It is not advisable, but if it is stored outside, the valve must be covered to protect it from heat and direct sunlight, with good ventilation to prevent humidity.
