 Flanged Type Double Flange Stainless Steel Butterfly Valve


The  Flanged Type Double Flange Stainless Steel Butterfly Valve is a thin, strong and fine-grained, stable, chromium-rich oxide film (protective film) formed on the surface of the butterfly valve, preventing the continuous infiltration of the oxygen atoms, and continuing to oxidize to obtain the anti-corrosion capability. For some reason, the film is constantly being destroyed, and the oxygen atoms in the air or the liquid constantly penetrate or the iron atoms in the metal are continuously separated out, and the loose iron oxide is formed, and the metal surface is constantly corroded.


For the clamping stainless steel butterfly valve, the structure is simple, the volume is small, the weight is light, the cost is low, the pneumatic butterfly valve is especially remarkable, it is installed in the high altitude dark channel, it is convenient to control and operate through the two-position five-way electric magnetic valve, and the flow medium can also be adjusted. The fluid resistance is small, the effective circulation area of the medium and large caliber pneumatic butterfly valve is large, the opening and closing is quick and labor-saving, and the opening and closing angle of the disc wrench can be completed at 90 angles. Because the force acting on the hand medium of the butterfly plate on both sides of the rotating shaft is close to equal, the torque produced is opposite, so the opening and closing torque is small, and good sealing can be achieved under low pressure. The sealing performance of butterfly valve sealing material is rubber, fluorine rubber, edible rubber, lined with four fluorine. The hard seal butterfly valve is a soft and hard laminated metal sheet with the heavy advantages of metal hard seal and elastic seal, and has excellent sealing performance at low temperature.


The Advantages Of Flanged Type Double Flange Stainless Steel Butterfly Valve

1.It is small and light, easy to assemble and disassemble and maintain, and can be installed at any position. 

2.The structure is simple and compact, the operation torque is small, and the 90-degree turn is opened rapidly.

3.The flow characteristic is in a straight line, and the regulation performance is good. 

4.The connection of the butterfly plate and the valve rod adopts a pin-free structure, and the possible inner leakage point is overcome. 

5.The outer circle of the butterfly plate adopts the spherical shape, so that the sealing property is improved, the service life of the valve is prolonged, and zero leakage is still maintained for more than 50,000 times under the pressure. 

6.The seal can be replaced and the seal is reliable to achieve the two-way seal. 

7.The butterfly plate can be coated according to the requirements of the user, such as nylon or polytetrafluoro. 

8.The valve may be designed to be flanged and connected to the clip. 

9.The driving mode can be manual, electric or pneumatic.
