  • Page 2: Installation

    KNIFE GATE VALVE - T-TAPPI SERIES ASSEMBLY DIRECTIVES Pressure Equipment Directive:: (PED) ART 4.3 /CAT.1 Potential Explosive Atmospheres Directive (optional): (ATEX) CAT.3 ZONA 2 y 22 GD. The T-TAPPI valve complies with the Directive on Equipment and Protective Systems for Potentially Explosive Atmospheres. In these cases the logo will appear on the identification label.
  • Page 3 KNIFE GATE VALVE - T-TAPPI SERIES fig. 1 Special care must be taken to respect the correct distance between the flanges and ensure they are correctly aligned and parallel (Fig. 2). The incorrect position or installation of the flanges can cause deformations on the valve’s body and this could lead to operating problems.
  • Page 4 KNIFE GATE VALVE - T-TAPPI SERIES ASSEMBLY POSITIONS (horizontal pipe) In horizontal pipes it is recommended that CMO valves be assembled in vertical position, although otherassembly positions are also possible. Position 1: This is the most advisable fig. 4 Position 8: The valve can be installed in this position but you are advised to contact CMO if this is necessary.
  • Page 5 KNIFE GATE VALVE - T-TAPPI SERIES ASSEMBLY POSITIONS (vertical/inclined pipe) CMO valves can be assembled in all positions; however, certain aspects must be taken into account: Positions number 1,2 and 3: In these positions, it is recommended to make a suitable support, because, due to the weight of the actuator, deformations may arise and this can lead to operating problems in the valve.
  • Page 6 KNIFE GATE VALVE - T-TAPPI SERIES ACTUATOR HANDWHEEL (Rising or Non‐Rising Stem and Stem with Gear Box) To operate the valve: Turn the handwheel clockwise to close or anticlockwise to open. CHAINWHEEL To operate the valve pull one of the chain’s vertical drops, taking into account that locking is carried out when the chainwheel turns clockwise.

  • Page 11 KNIFE GATE VALVE - T-TAPPI SERIES LUBRICATIONS It is recommended to lubricate the stem twice a year by removing the protection cap and filling it with grease up to half its volume. After the maintenance and in an ATEX zone, you must check the electrical continuity between the pipe and the rest of the valve’s components, such as the body, gate, stem, with EN 12266-2 Standard, annex B, points B.2.2.2.
