Against condensation butterfly valve

●  Design The Characterstic

DF series butterfly’s valve gives play to the superior function in preventing forming revealing. Technology and unique multi-level more and more close contact-type valve flat that experienoe develop that utilize for many years accumulating, synthesize other multiple DF series butterfly valve of technology more and more field substitute valve, have characteristic with simple construction and having long perfor mancelife.

●  Design The Characterstic

Urique multi-level advances gradually the contact type valve seat design, causes the valve board gradually to contact the valve seat in the closure process, during guarantee good sealing property,reduces the noressertial torque, thus lengthens the valve seat the servicelife.

●

The ultra light aluminum alloy valve body, the torque is small;

●

The usr installment is convenient, ceases the rust edipse;

●

The torque reduced realizes the drive weight to be light and the miniaturization;

●

Is in sole possession of the valve level packing ring prevented the fluid divulges;

●

The different material quality valve seat, the adaption different operating mode,has the good anticorrosion harmoniously to seal the performance.

●

The ball-and-socket valve board path causes the valve rotation to br flexible freely

The valve board is becomes according to a complete sphere processing, the packing surface each part all is a aphencal surface part, even if is valve board on, under the peak axial packing surface place is not exceptional, such packing surface when seal, although has the contact, actually is quite smooth, therefore the moment offorce reduced, the sealing property improved, specially the axial seal place friction reduced, used this technical the valve seat life to increase three times.
