this manual butterfly valve butterfly plate installed on the diameter of the pipe direction. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 & deg; - 90° Between, rotate to 90 & deg; When the valve is fully open. Butterfly valve has simple structure, small volume, light weight, only by a few parts. And only need to rotate for 90 & deg; Can quick opening and closing, the operation is simple, at the same time, the valve has good flow control characteristics.

1。 Butterfly valve is placed in between the two flanges, pay attention to the alignment hole

2. Butterfly valve is placed in between the two flanges, pay attention to the alignment hole

3. Flange welded to the tube road

4. Flange welded to the tube road

5. Completely fixed flange welding to

6. Completely fixed flange welding to

7. Tighten 4 for bolt and nut, diagonal mutual twist, debug the valve installation position

8. Switch valve to ensure that the valve plate free to switch, not stuck

9. Diagonal to each other to turn the nut to complete the installation, the installation after the switch again several times, to ensure that the use of the valve without exception.

manual butterfly valve structure characteristics of the three to eccentric *

(1) design between the sealing surface friction drive, prolong the service life of the valve.

(2) generated by the torque of the elastic seal.

3. Clever wedge design allows for automatic sealing Industrial Valves has closed more and more tightly, compensatory, zero leakage between the sealing surface.

(4) small volume, light weight, light operation and ease of installation.

(5) according to user requirements with pneumatic, electric devices, meet the needs of the remote control and programmed control.

6 replacement parts material can be applied to all kinds of medium, and can be carried out lining anticorrosion ( Lining F46, GXPP, PO, etc. ) 。

7) continuous structure diversification, the clamp, flange, butt welding.

installation and maintenance of manual butterfly valve when installed, the disc will stop in closed position. Open position should be according to the butterfly plate to determine the Angle of rotation. Butterfly valve with a bypass valve, open open the bypass valve should be taken before, should be in accordance with the manufacturer's installation instructions for installation, weight big butterfly valve, should set up a solid foundation.

the scope of application of manual butterfly valve is widely used in petroleum, chemical, food, medicine, paper making, water and electricity, shipbuilding, water supply and drainage, metallurgy, oil, energy, such as the pipeline system, applicable to a variety of corrosive gas, liquid, half liquid and solid powder medium.

manual butterfly valve material choose

1, the valve body material: gray cast iron, nodular cast iron, cast steel, aluminum alloy, stainless steel, etc. ;

2, the valve material: duplex stainless steel, nylon 11 plate, galvanized sheet, aluminum bronze;

3, seat material: nitrile rubber, epdm rubber, fluorine rubber, silicone rubber, ptfe
