Wafer Type Hard Sealed Butterfly Valve D373H

The opening and closing part of a butterfly valve is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening and closing or adjusting. The advantages of butterfly valves include simple structure, small volume, light weight, small installation size, and quick opening and closing.
Triple eccentric butterfly valve refers to a butterfly valve where the valve stem axis simultaneously deviates from the center of the disc and the center of the body, and the sealing pair is an inclined vertebra.
The triple eccentric butterfly valve with a wafer worm gear hard seal adopts a U-shaped stainless steel sealing ring, and the internal precision elastic sealing ring is in three-dimensional eccentric contact with the polished butterfly plate. Solved the problem of sliding contact friction on the sealing surface of traditional eccentric butterfly valves during opening and closing from 0 ° to 10 °, achieved the effect of separating the sealing surface of the butterfly plate at the moment of opening and sealing when the contact is closed, and extended service life and sealing performance *.
Performance characteristics of D373H butterfly valve with wafer type worm gear hard seal:

1. The metal hard sealed butterfly valve has a simple and compact structure, light weight, easy installation and disassembly, and convenient maintenance;
2. The clamp type hard sealed butterfly valve adopts a stainless steel U-shaped sealing ring, which has a certain elasticity. Regardless of high or low temperature, it has excellent sealing performance with the butterfly plate;
3. The three-dimensional eccentricity of the worm gear wafer type butterfly valve has been strictly calculated, and the U-shaped sealing ring has almost no friction with the butterfly plate, with a long service life and a function of tightening the valve as it is closed;
4. The sealing surface of the butterfly plate is made of cobalt based hard alloy, which is wear-resistant and has a long service life;
5. Metal hard sealed butterfly valves have high temperature resistance, low temperature resistance, and corrosion resistance.
