ZSSDW series pneumatic elastic metal sealed butterfly valveDetailed product description：

ZSSDW series pneumatic elastic metal sealed butterfly valve
Product specifications: DN50-DN1000
Product features: ZSSDW series pneumatic elastic metal sealed butterfly valve adopts a "U" - shaped stainless steel sealing ring. The precision elastic sealing ring of the valve is in contact with the chrome plated polished butterfly plate sealing surface, and the organic combination of the two has the characteristics of high temperature resistance, high pressure resistance, low temperature resistance, etc. Therefore, it is widely used in heating, steam supply, water supply, and pipelines for different media such as gas, oil, acid and alkali with medium temperature ≤ 550 ℃ to adjust flow, cut off or connect fluids

ZSSDW series pneumatic elastic metal sealed butterfly valve detailed introduction:
The double eccentric sealing structure offsets the axis of the valve stem and the sealing surface of the butterfly plate by a dimension A, and offsets the axis of the valve body channel by a dimension B. When the butterfly plate is opened from 0 ° to 90 °, the sealing surface of the butterfly plate will detach from the sealing surface of the valve seat faster than a single eccentric. When the butterfly plate rotates from 0 ° to 8 ° to 12 °, the sealing surface of the butterfly plate can completely detach from the sealing surface of the valve seat. Therefore, during the opening and closing process of the butterfly valve, the relative mechanical wear between the sealing surface of the butterfly plate and the valve seat, the extrusion angle stroke, and the mechanical wear and extrusion deformation are reduced, and the sealing performance and service life of the butterfly valve are improved.
1. Adopting a "U" - shaped stainless steel sealing ring, the valve seat has a certain degree of elasticity, and it has excellent sealing performance with the butterfly plate under high and low temperature conditions.
2. It is a metal to metal wire sealed butterfly valve, and the sealing surface of the butterfly plate is made of welded stainless steel or welded hard alloy. The sealing surface is wear-resistant and has a long service life.
3. The butterfly valve has excellent sealing performance, temperature resistance, pressure resistance, wear resistance, and corrosion resistance due to its streamlined design, connecting rod, wear-resistant shaft sleeve, and other parameters.
4. This valve can be designed for flange connection and clamp connection.
5. The driving mode can be selected as manual, electric or pneumatic.
