D673F D673F-10 D673F-16 Pneumatic butterfly valve

Overview of D673F D673F-10 D673F-16 Pneumatic butterfly valve

D673F D673F-10 D673F-16 Pneumatic butterfly valve adopts offset valve stem and eccentric butterfly plate. When the valve seat is opened at any position, there is no contact between the valve seat and the butterfly plate, eliminating the wear at the upper and lower ends of the valve seat; It reduces the operating torque and the requirements for operating machinery, and has a fire-proof structure. It can also provide such valves for chlorine, oxygen, high vacuum and corrosive media and low temperature.

Features of D673F D673F-10 D673F-16 Pneumatic butterfly valve

1. The butterfly valve has the advantages of short structure size, small volume, light weight and light operation.

2. The butterfly valve adopts a three eccentric structure, which has the function of tightening when closing. The butterfly plate can bear pressure in both directions, with excellent sealing performance and zero leakage. After opening, ensure that the sealing surface is completely out of contact and protect the sealing surface from damage.

3. The body valve seat structure is adopted to reduce the direct contact of the valve seat with the medium, so as to reduce the erosion degree of the valve seat and prolong the service life of the valve seat.

4. The valve seat is made of laminated stainless steel sheet and graphite sheet. This structure can effectively prevent the influence of small solids in the medium and the bite of the sealing surface caused by thermal expansion. Even if there is slight damage, there will be no leakage.

5. The sealing pair is fixed by oval distribution of bolts, which not only makes the positioning accurate, but also makes each bolt bear the force evenly, and eliminates the loosening and leakage of the sealing pair caused by uneven stress distribution.
