Z41W Hard-sealed gate valve

Product Overview

The gate valve is the most commonly used shut-off valve, primarily designed to connect or block media in pipelines and unsuitable for regulating flow rates. Employed in industrial pipelines, it controls media flow and interruption through the opening and closing of its gate plate. It finds applications in various industries such as petroleum, chemical, and power sectors for cutting off or connecting pipeline media.

Product Features

Optimize the structural design to facilitate effortless valve operation

The medium flow direction is unrestricted, causing no turbulence or pressure reduction. The fluid resistance is low, resulting in minimal scouring and erosion of the sealing surfaces by the medium.

Simple in shape, short in structural length, excellent in manufacturability, and widely applicable.
