This series of butterfly valves are suitable to be used for industrial pipeline as two-way open-closing and regulating devices.The scope of regulation is from 4o°to 90°fully open.If the valve is one-way used,the recommended pressure direction of closing is shown on fig.
features:
1.The disk is truss framed with two-plate and flow-resistent is lower.
2.It has reliable sealing structure for two-way stopping without any leakage.
3.The axle sleeves are self-lubricanted bearing. Oiling is not need and friction drag is small during operation.
4.Rubber sealing can be replaced on pipeline without removing the valve (DN>700).
5.Several kinds of actuators with reliable performance and agile operation are supplied for the liser's selection. Wear-resisting and corrosion-resisting. |
