The basic type of the plant has two types: D71 series center line butterfly valve, D73 series eccentric butterfly valve. The two piece on the valve combination, the valve seat and valve liner valve work, integration, only full plastic seat and lining plastic disc contact with the media, the valve can withstand the corrosion of lining material is introduced, the SI rubber elastic pad using quadrupole seal structure and the sealing surface with high temperature resistance and aging, fully meet the zero leakage medium.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
1, the center line butterfly valve for the entire butterfly plate and the valve seat in the 360 degree circle concentric (center line), with two-way sealing function, pressure, flow can be freely adjusted;
2, eccentric butterfly valve for the two-dimensional direction of the cam effect of the product will make the sealing pair produce enough sealing pressure, and with the increase of the working pressure, the sealing effect is more ideal;
3, four load elastic seal, to ensure that the valve inside and outside the zero leakage.
A: shaft and butterfly valve integrated outer lining F46;
B: by O elastic ring end surface of the shaft head and shoulder rigid washer, elastic rubber pad combination;
Combined radial c: axis using O type ring and a metal sleeve;
The d: valve seat is inlaid with the body groove of the elastic strip.
4, the use of flexible gasket positioning accuracy, simple structure. (* using the O loop to prevent accidental leakage).
