D341J rubber-lined butterfly valve

Main overview

In addition to the cutting and intercepting of the lined flanged butterfly valve, the sealing performance has been regarded as the main index of evaluation in recent years and is favored by the market.

1. There are two basic types, namely D71F4 and D71F46 (middle line) and D71F4 and D71F46 (eccentric) fully lining type wafer type butterfly valves. The two-piece valve type combination is used, and the valve seat and valve body lining are integrated. When the valve is working, only the all-plastic valve seat and the lining plastic disc are in contact with the medium. The product can withstand any medium corrosion other than molten alkali metal and elemental fluorine. The D71F4 valve stem is also integrated with the butterfly plate (forging), and the surface is evenly wrapped. A layer of FEP. The valve body passage has smooth inner surface, low fluid resistance, high CV value, strong circulation capacity and moderate torque. Zero leaks.

2. The D71F and D41F flanged valve body are fully lining, and the butterfly plate is a stainless steel lining type butterfly valve.

3, D343F flange connection double eccentric fully lined butterfly valve.

Main Features

1) Simple structure in linear type ,easy in installation and maintation. 

2) Adopting advanced world famous brand components in pneumatic parts ,electric parts and operation parts. 

3) High pressure double crank to control the die opening and closing. 

4) Running in a high automatization and intellectualization,no pollution 

5) Apply a linker to connect with the air conveyor ,which can directly inline with filling machine . 

Structural features

1. The middle line butterfly valve is concentric (middle line) in the 360° circumference of the whole butterfly plate and the valve seat, and has a two-way sealing function, and the pressure and flow can be freely adjusted;

2. The cam effect generated by the eccentric butterfly valve in the two-dimensional direction eccentricity will cause the sealing pair to generate sufficient sealing specific pressure, and as the working pressure increases, the sealing pair generates sufficient sealing specific pressure, and as the working pressure increases The sealing effect is more ideal.

3, four-stage loading elastic seal, absolutely guarantee zero leakage inside and outside the valve;

a, the special transition curve of the joint between the shaft head and the disc and the reasonable interference of the valve seat;

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

c. The radial direction of the shaft is a combination of an O-ring and a metal pad;

d. The valve seat is set in the valve body groove with the elastic strip;

4. It adopts adjustable marble positioning, accurate positioning and simple structure. (O-rings are used to prevent accidental leakage)

5. Flange connection double eccentric butterfly valve is used for high pressure applications.
