Note: *The hexagonal valve at the valve body is a structural element that serves to lock and prevent reversing when the valve is released. Never turn the hexagon. To
open the discharge valve, a manually operated perimeter cut-out screw is provided. Anticlockwise, the valve opens and closes clockwise.
In case it is necessary to provide dismountable joints application in the valve in the piping, weld the pipe matching the combined reducer with a thread on the valve. If necessary, it is possible to dismantle and exchange the valve easily.
