Important Notes Usage for the intended purpose Use the shut-off valve GAV 54 F only for isolating and throttling neutral gases, steam, vapours and liquids within the specified pressure and temperature ratings and check the corrosion resistance and chemical suitability for the application in question. Safety note The equipment must only be installed and commissioned by qualified and competent staff.
Explanatory Notes Scope of supply GAV 54F Shut-off valve GAV 54F Installation manual Description Maintenance-free bellows-sealed shut-off valve with straight-through body, flanged to EN 09-. The shut-off valve is equipped with a stainless steel bellows seal and a safety stuffing box made from pure graphite.
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:...
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).
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.
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.
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.
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.
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.
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.
