  • Page 8: Installation

    Installation GAV 54F Responsibility for positioning and installing the valves always lies with the engineering company, construction company or operator/user. Planning and installation errors may impair the reliable function of the valves and pose a substantial safety hazard. For this reason it is particularly important to observe the following:...
  • Page 9: Danger

    Installation - continued - Attention - continued - When the valve is installed outdoors, sufficient weather protection must be provided to prevent corrosion and other damage caused by penetrating moisutre. When painting pipes or equipment, do not apply paint to the stem and plastic components (valve function will be impaired).
  • Page 10: Danger

    Valves with pilot plug must always be installed so that the pressure to be sealed off lies above the plug. Commissioning Procedure GAV 54F Prior to commissioning / start-up compare the material, pressure and temperature data on the valves with the operating conditions of the piping to check the material's chemical resistance and stability under load.
  • Page 11: Attention

    Commissioning - continued - Attention As the valve can be damaged by applying excessive forces, it is not allowed to use additional levers to move the handwheels of nominal valve sizes up to and including DN 5. On all nominal sizes greater than DN 5, suitable additional levers may be used up to the following torque limits: [Nm] Hex.
  • Page 12: Maintenance

    Maintenance GAV 54F Repair and maintenance work must only be performed by skilled, properly trained personnel. It is imperative that the following safety instructions and the danger note on page 4 be observed for all servicing and maintenance work to be performed.
  • Page 13: Spare Parts

    Spare Parts GAV 54F No spare parts are available for shut-off valves up to DN 50. A faulty shut-off valve must be discarded and replaced by a new one. Attention All repair and maintenance work shall be performed by skilled, properly trained personnel using suitable tools and original spare parts.
  • Page 14: Transport And Storage

    Transport and Storage Transport The valves are closed when supplied and, if required, the line connection ports are capped. The valves are ready for operation upon delivery. Attention For transport and interim storage, the valves must always be kept in the closed position, and the line connection ports must be covered with suitable material (e.
  • Page 15: Hoisting The Valve For Installation Into Horizontal Pipeline

    Transport and Storage - continued - Hoisting the valve for installation into horizontal pipeline Straps  and  must be tied around the valve body. To hold the valve in the position shown below and to avoid tilting, both straps should be routed to the lifting hook between the handwheel arms.
