Bi-directional wafer butterfly valve exported to Japan
Recently, we have developed a bi-directional wafer butterfly valve for Japanese customers，the medium is circulating cooling water, temperature + 5℃.
The customer originally used unidirectional butterfly valve, but there are several positions that need really need bi-directional butterfly valve, so our customer asked us to re supply the bi-directional wafer butterfly valve in these positions without changing the face to face dimensions.
After THT technical department discussion, we decided to use the original unidirectional sealing mold to process the bi-directional sealing butterfly valve. As a result, we succeeded, PN25 positive pressure back pressure 1:1.
