Valvefac DN100 (4in) electric knife gate valve with WCB wafer flange is a specialized industrial valve engineered for reliable shutoff and flow control in media containing solids, dust, or particles—an area where traditional gate valves often clog or fail. Featuring a knife-like gate  and wafer-style flange connection, this valve combines the structural strength of WCB (cast carbon steel) with electric actuation, enabling automated, low-maintenance operation across medium-pressure systems.

Designed to handle diverse media including water, gas, dry dust, and small solid particles (≤3mm), the valve operates within a pressure range of PN16 (1.6MPa) and temperature range of -20℃ to +150℃—making it suitable for harsh industrial environments where manual valve operation is inefficient or unsafe. Compliant with global standards such as ASME B16.34, API 600, and GB/T 12234, it integrates seamlessly into municipal, mining, chemical, and power sector pipelines, delivering consistent performance in both on-off and basic throttling applications.
