Installation Precautions. Shut-off valve GLV-1.
• The product should be stored in a clean, ventilated area with low humidity.
• Installation must be carried out by trained personnel using personal protective equipment.
• The product can be used for "full open" and "full close". Using the product to open in an intermediate position may damage the ball and seat.
• Avoid distortions between the product and the pipeline, which could damage the threaded connections.
• During transport or storage of the product, leakage may occur through the sealing washer, which was unscrewed as a result of stress relief in the seal. Tighten the sealing washer before use.
• When installing, use a threaded seal (eg sealing tape). The sealant must be suitable for the temperature, medium, etc.
• If there is a possibility of freezing, take measures to prevent it or drain the water (after use).
• Slip on the stop valve stem can cause particles of sealing material to enter the process fluid when opening and closing. Install a filter downstream of the shut-off valve to prevent mixing of sealing material particles with the medium.
• The shut-off valve can be used in a fully open / fully closed configuration. When the valve is operated in intermediate positions, erosive wear of the body and seat is possible.
• The valve is operated by hand. Do not use additional handles for this. This may damage the product.
• Use a suitable tool such as a wrench to connect the product. Do not use a pipe wrench. This can lead to incorrect operation of the product (see Fig. 1.)
