Deskripsi
Katup Kupu-kupu Wafer D71X dengan Dudukan Lembut
The D71X soft-seated wafer butterfly valve is a compact and lightweight valve
designed for reliable flow regulation and shut-off in industrial water supply
and drainage systems. With a 90-degree quarter-turn operation, the valve can be
opened and closed quickly with low operating torque.
WDL Valve supplies D71X soft-seated wafer butterfly valves for water plants,
power plants, steel mills, paper mills, chemical processing, food processing
and other industrial applications. The valve provides reliable sealing, long
service life and convenient installation in limited spaces.
