DA371F3/DA971F3 Fluorine lined Plastic Butterfly Valve Introduction:

DA371F3/DA971F3 Fluorine lined Plastic Butterfly ValveUsing a PTFE lined butterfly plate with a spherical sealing surface and a silicone rubber gasket at the base of the valve seat to adjust the sealing performance of the valve; This valve is easy to operate, has tight sealing performance, and is super

Long service life; Can be used to quickly cut off or adjust flow. Suitable for occasions that require reliable sealing and good adjustment characteristics.

DA371F3/DA971F3 Fluorine lined Plastic Butterfly Valve Features:

1. The midline butterfly valve is concentric with the entire butterfly plate and valve seat within a 360 ° circumference (midline), with bidirectional sealing function, and pressure and flow can be freely adjusted;

2. The cam effect of the eccentric butterfly valve, which is a two-dimensional eccentric product, will generate sufficient sealing pressure in the sealing pair, and with the increase of working pressure, the sealing effect becomes more ideal;

3. Four level loading elastic seal ensures zero leakage inside and outside the valve.

a: Shaft and butterfly valve integrated outer lining F46;

b: The end face of the shaft head adopts a combination of elastic O-ring, rigid washer at the shaft shoulder, and elastic rubber pad;

c: The radial direction of the shaft adopts a combination of O-ring and metal shaft sleeve;

d: The valve seat is embedded in the valve body groove with elastic strips.

4. Using elastic gaskets for accurate positioning and simple structure. The use of O-rings is a safety measure to prevent accidental leakage.
