For solvent or welded connections, ensure also that the parts to be connected are of the same material and that the correct solvent or welding tools are used. To install the valve, follow best installation practice recommendations provided on the Cepex website, paying specific attention to thermal expansion and pipe alignment. - Page 9 EXTREME ELECTRIC BUTTERFLY VALVE OPERATION OF THE ACTUATOR The motorised valve consists of an electronic actuator mounted on a conventional valve. OPERATION. When an electric signal is received, the motor turns to either “OPEN” or “CLOSE” depending on the switching signal until the internal cam connects to the microswitch, bringing the motor to a stop.
- Page 10 EXTREME ELECTRIC BUTTERFLY VALVE OPERATION AND MAINTENANCE INSTRUCTIONS It is recommended that the condition of the sealing gasket be regularly checked, since it may show signs of mechanical wear due to pressure, handling and contact with the liquid. The sealing gasket should be greased in the disc contact area (the grease must be compatible with the materials of the gasket and the disc).
