◆ The valve stem downward running is the closing direction of the valve.
◆ Make sure the pipe is clean and without oxide and metal after welding before installation.
◆ It must be at the same point and free from shocks when connect the pipe and valve body. The flow direction should be same as the direction of the label.
◆ When the actuator is vertically installed on the valve,please avoid installing it under the valve to leave enough space for daily maintenance(like remove the actuator).
◆ Cut off the electricity to make sure there is no pressure in the water system when maintenance.
