Wafer-Type Soft-Seated Butterfly Valve
The Wafer-Type Soft-Seated Butterfly Valve is a cost-effective, easy-to-maintain valve featuring a soft seal. It utilizes a detachable, core-less (soft-backed) rubber seat design with a tongue-and-groove configuration; this ensures the seat is securely anchored to the valve body—preventing deformation—while also facilitating convenient in-line replacement. Its lightweight wafer-style structure, excellent sealing performance, and ultra-low operating torque make it a preferred choice for fluid control and water system piping. It is widely used in water treatment plants, power plants, steel mills, and the paper, chemical, and food industries for water supply, drainage, and gas pipeline applications.

Wide edge soft back seat, excellent installation and sealing performance
The core advantage of the soft-backed wafer butterfly valve lies in its wide-edge sealing band design. Compared with the traditional hard-backed valve seat, the soft-backed valve seat has a wider contact surface with the pipe flange. It does not need to be equipped with a special flange for butterfly valves during installation to achieve excellent sealing effects. The valve seat rubber has a high rubber content and has been tested more than 10,000 times without leakage after simulated opening and closing tests. The valve seat can be removed and replaced manually without the need for professional equipment, which greatly reduces maintenance difficulty and cost. The wide-edge design also provides a larger sealing compensation margin, which can effectively absorb the slight displacement caused by the thermal expansion and contraction of the pipeline, ensuring sealing reliability in long-term use.

Sealing surface design, no gasket required for installation
The soft backrest valve seat extends outward on both sides, covering the structural end surfaces on both sides of the valve body, forming a wide rubber flange sealing surface. When connected to the pipe flange, the end face of the valve seat can act as a perfect gasket seal. During the installation process, there is no need to purchase and install additional flange sealing gaskets, which not only simplifies the on-site construction process, but also reduces the potential risk of flange leakage.

Excellent wear and tear resistance and multiple materials available
Thanks to the strong support of the rubber by the tongue and groove structure, the friction and extrusion of the valve plate against the valve seat is evenly dispersed when the valve is opened and closed, which greatly improves the tear and wear resistance of the valve seat. We can provide a variety of high-quality valve seats including EPDM, NBR, FKM, etc., as well as valve plates made of ductile iron, stainless steel, duplex steel, etc., which can easily adapt to a variety of media conditions ranging from pure water, industrial sewage to weak acids and alkalis, oils, etc.
