EGZ Series Electric Flange Gate Valve
Product Overview
<The electric flange gate valve is a linear motion valve, paired with a Z-type multi-turn actuator, available in both on/off and intelligent types. This valve is easy to operate and is one of the most common shut-off valves. It uses the up and down movement of the gate to connect or disconnect fluid media in the pipeline. Widely used in industries such as power, metallurgy, petroleum, chemical, papermaking, and wastewater treatment.
Product Features
1.Low flow resistance, with minimal沖刷 and erosion of the sealing surface by the medium (high gate opening).
2.Strong opening force, excellent sealing performance, unrestricted medium flow direction, no turbulence, and no pressure drop.
3.Simple and clear structure, good manufacturability, and wide applicability.
4.Low torque required for valve closure.
