ADVANTAGES

Aluminum handle wafer butterfly valve is a butterfly valve with aluminum material handle,which has low torque,long life cycle.Except the handle material, aluminum handle wafer butterfly valve have the same features as other handle wafer butterfly valve.

Product Advantage

1,The patent rubber seat we use was taken Bundor two years to reserch and develop independently.

2,Bundor rubber seat is used more widely and able be matched with various kinds of flanges. No need to use special flange for butterfly valve, it can be connected perfectly with common slip on flange.

3,Bundor patent body can meet various standards such as JB, DIN, GOST, ANSI, BS, JIS etc. For top flange standard, we offer GB, ISO5211. More beautiful appearance, wider working conditions.

4,Bundor uses Germany Bayer brand EPDM rubber as raw material for valve seat. That makes butterfly valve has superior rebound resilience and tensile force. 100% no leakage after open and close over 10000 times.

5,All the materials of bolt, nut and pin are stainless steel. The corrosion resistance 10 times better than ordinary material.

6,The patent rubber seat is easier to install. Compared with ordinary rubber seat, it has double width of sealing surface and wider contact surface with flange waterline.
