• 1．When installing ball valve, the max torque ≤15Nm. If the ball valve is out of operation for a long time, and the torque value of first on or off is the max torque. Or you can choose ball valve with elastic sealing.
• 2. When installing butterfly valve, the max torque≤13Nm. Because the torque value will increased by 10-20% after installing.
• 3．When installing direct mount mode valve, the hole deep ≤15mm. It requires cutting if the output shaft is longer than 15mm.
• 4. Please pay attention to the following items if you install the bracket and coupling by yourself:
• ※ The intensity of bracket should meet the using requirements: the bracket twisting extent ≤0.2mm in the process of on or off.
• ※ The parallelism of bracket ≤0.5mm.
• ※ When processing the shaft hole at both end of the coupling, it is necessary to ensure the accuracy and concentricity. The purpose is to make sure the mechanical hysteresis ≤10°, otherwise it will cause the actuator unable to work.
• 5. Screw should be installed spring washer、flat washer, and we suggest you daub some glue cement around the screw in case of screw loosening.
• 6. After installation, user should switch the valve on and off one time with handle device first. Modifying the valve after make sure it works well
