Two-Piece Butterfly Valve

Stainless steel butterfly valve with a two-piece body design. For media shut-off in liquid cooling and water supply/drainage applications. Lightweight construction with quick open/close operation.

Nominal pressure	PN10
Temperature range	-20 ℃ to 100 ℃
Test standard	GB/T 13927-2022

Product Description

The two-piece butterfly valve is designed for quick media shut-off in non-critical branch circuits and water supply/drainage lines. Its compact, lightweight structure ensures easy installation in confined spaces. The valve features low fluid resistance, fast opening and closing, and low operating torque for smooth manual actuation. A reliable EPDM sealing ring provides effective shutoff, while the degreased body meets the cleanliness requirements of liquid cooling systems.
