Fluorine - lined butterfly valve main advantages and characteristics

Fluorine lined butterfly valve main advantages, simple structure, small size, light weight, low cost, fluorine lined butterfly valve the full fluorine lined butterfly valve characteristics are particularly significant, installed in the upper air tunnel, after two five-way solenoid valve control easy operation, can also adjust the flow medium. The fluid resistance is small, the large diameter pneumatic disc valve when fully open effective circulation area is large, fast opening and closing labor saving, disc lever rotation 90 Angle can complete the opening and closing.

Due to the rotation axis disc plate hand medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, disc valve sealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for soft hard cascading metal hard seal butterfly valves with metal sealing and elastic sealing heavy advantage, Excellent sealing performance regardless of low temperature.

As chemical corrosion prevention of synthetic rubber in the application of butterfly valve fluorine-butterfly butterfly valve, all because of polytetrafluoroethylene (PTFE) have strong corrosion resistance, stable performance, not easy to aging, low friction coefficient, easy to shape, size stability, and can also be through filling, add the appropriate material to improve its comprehensive performance, get better strength, lower friction coefficient of metal hard seal butterfly valve.

Therefore, polytetrafluoron as the representative of polymer polymer materials and their filling modified materials have been widely used in the fully incited rear line butterfly valve, so that the performance of butterfly valve has been further improved, there is a wider range of temperature, pressure, sealing performance, longer service life of fluorine lined butterfly valve.

Fluorine lined valve classification:

Fluorine-butterfly valves are divided into: pipe clamp valve, diaphragm valve, pneumatic butterfly valve lining the lining the lining ball valve, check valve, the lining rubber fluorine globe valves, plug valves, the lining lining wedge gate valve, diaphragm valve, butterfly valve, ball valve, swing check valve, ball core, pneumatic rubber lining, lining fluorine plastic diaphragm valve (often closed), dc line with rubber diaphragm valve, adjustable lining fluorine plastic packing type butterfly valve, fluorine-butterfly plastic cut-off valve, etc.

Fluorine lined butterfly valve features:

1, novel design, reasonable, unique structure, light weight, fast opening and closing.

2, operating torque is small, easy to operate, labor-saving dexterity.

3, can be installed in any position, convenient maintenance.

4, sealing parts can be replaced, reliable sealing performance to achieve two-way sealing zero leakage.

5, sealing material aging resistance, corrosion resistance, long service life and other characteristics. With a standard
