D341XOverview of Soft Sealed Butterfly Valve:
Soft-seated butterfly valves, as components for cutting off pipeline systems and controlling flow, have been widely used in many fields such as petroleum, chemicals, metallurgy, hydropower, and more. Among the known butterfly valve technologies, the sealing form usually employs a sealing structure, with sealing materials being rubber and the like. Due to the limitations of structural features, they are not suitable for industries requiring high temperature, high pressure resistance, as well as corrosion and wear resistance. An advanced butterfly valve available now is the three eccentric metal hard-seated butterfly valve, where the valve body and seat are integral components. The sealing surface of the seat is surfacing-welded with temperature and corrosion-resistant alloy materials. Multi-layer soft-laminated sealing rings are fixed on the valve plate. Compared to traditional butterfly valves, this type offers the advantages of high-temperature resistance, easy operation, friction-free opening and closing, and compensation for sealing as the torque of the transmission mechanism increases during closure, thus improving the sealing performance and extending the service life of the butterfly valve.
D341XSoft-seated butterfly valveFeatures:
：1Compact and lightweight, easy to disassemble and maintain, and can be installed at any location.
2Simple and compact structure, with low operation torque.90The degree rotation starts quickly.
3Flow characteristics approach a straight line, with good regulating performance.
4The butterfly plate and valve rod connection employs a pinless structure, eliminating potential internal leakage points.
5Sealings are replaceable and provide reliable double-sealing.
6Blade plates can be coated with layers as per customer requirements, such as nylon or polytetrafluoroethylene.
7The valve can be designed for flange connection and clamp connection.
8Manual, electric, or pneumatic drive options available.
The Difference Between Hard and Soft Seals:
Rigid-seated butterfly valve:The sides of the sealing pair that are made of metal or other harder materials are referred to as"Hard-sealed".This sealed seal has poor sealing performance.,But high-temperature resistant,Wear-resistant,Excellent mechanical properties.As:Steel+Steel;Steel+Copper;Steel+Graphite;Steel+Alloy steel;(The steel here may also be cast iron.,Cast Steel,Alloy steel may also be surfacing焊,Coated alloy).
Soft-seated butterfly valve:The seals are made of metal on both sides.,On the other side is an elastic non-metallic material referred to as"Soft-sealed".This sealed seal has good sealing performance.,Not heat-resistant,Easy-to-wear-out,Poor mechanical properties.As per your request, there is no content provided to translate.

The advantages of the soft-seated butterfly valve are its excellent sealing performance, while the drawbacks include susceptibility to aging, wear, and a shorter service life.
The hard-seated butterfly valve has a long service life, but its sealing performance is relatively inferior to that of soft-seated valves.
