Maintenance and control- Control the valves yearly.- Change the gaskets after each disassembling.

- Any maintanance action must be carried out when the installation is in the atmospheric pressure.- Cut energy supply of the actuators.- The valves are always delivered with the loosened packing gland. Before any use, tighten the gland gradually.- After setting under pressure on line, check the leakage on the level of the packing and tighten if necessary.- Be sure that the position indicator is visible.- Assembly in specific end of line.- Respect the recommended positions of assembly.- Respect the disassembling direction.- In the event of prolonged storage or of weak frequency of operation, lubricate the valve stem regularly.- Take care of assembly of the protection tube of stem at the time of the first installation. The grease reserve of the stem is ensured in the protection tube, offering a regular greasing.- When assembling of an electric motor on the valve, take care to lubricate the nut of the motor and the stem of the valve.
