• The valve must be mounted so that the stem is in a vertically upward or horizontal position.
• Valves must be opened manually. The valve is designed to withstand high internal pressure. However, the piping system must be designed to reduce the risk of hydraulic pressure caused by thermal expansion.
• When making valve connections, suitable welding methods should be used with materials compatible with the valve body. After welding is complete and before the valve is fully assembled, clean the valve internally to remove welding residues.
• Be careful not to damage the Teflon conical ring.
• The valve housing must be free from stresses (external loads) after installation.
• The outer surface of the valve housing must be protected against corrosion with a suitable protective coating after installation and assembly.
• Check that the shaft is free from scratches and impact marks.
• If the Teflon cone ring is damaged, the entire cone assembly must be replaced.
