Soft Seat Wafer Butterfly Valve

Product Features and Applications

Structural Features

Multi-Standard Design

Multi-standard butterfly valves refer to valves designed to conform to multiple international standards, such as ANSI, DIN, JIS, and GB. This allows the butterfly valve to be used in pipeline systems adhering to different standards, providing greater versatility.

Wafer-style Connection

This butterfly valve features a wafer-type design, where the valve is sandwiched between two flanges using bolts. This design simplifies installation and is suitable for use in confined spaces for both installation and maintenance.

Soft Sealing Design

The sealing surfaces of the valve typically use soft materials such as rubber, fluororubber, EPDM, or PTFE. These materials offer excellent sealing performance and effectively prevent medium leakage under low and medium pressure conditions.

Compact and Lightweight

The soft seat wafer butterfly valve features a compact and lightweight design, offering ease of operation and reducing installation space requirements. This design also helps to lower the overall weight of the piping system.

Performance Features
