Low - Torque Flange Type Butterfly Valve
Application
1.Excellent bidirectional sealing performance, low torque value, and superior machining performance of parts
2.Flow characteristics tend towards a straight line, with good regulation performance
3.The flange connection is easy to install, and can be installed vertically or horizontally
4.The diversity of sealing auxiliary materials available for users to choose
5.Valves can be used as venting valves at pipe ends, with reliable performance
6.The valve seat sealing ring is organically integrated with the valve body, giving the
7.valve a longer lifespan
8.Good anti erosion performance, suitable for harsh working conditions, and can be 9.used for medium interception and regulationdiv>
