ELECTRICALLY OPERATED 2-WAY BUTTERFLY VALVE -1250 SERIES

We are totally committed to providing highest quality valves and outstanding service to our customers. Complete customer satisfaction is our goal.

                Incorporating the latest in valve manufacturing technologies Sude assures a consistent, high quality valve that will provide years of trouble-free service.

                 A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage.
