Bevel gear drive knife gate valve
The Bevel Gear Drive Knife Gate Valve is engineered for industrial pipelines transporting slurry, pulp, and particle-laden fluids. Its bevel gear mechanism allows effortless manual operation of large valves. Constructed from corrosion- and wear-resistant materials, the valve ensures tight sealing, long service life, and reliable performance in mining, chemical, and wastewater systems.
Bevel gear drive knife gate valve
Bevel Gear Drive Knife Gate Valves combine a sharp knife-edge gate with a bevel gear actuator, enabling smooth operation of large-diameter valves with minimal manual effort. The valve is suitable for abrasive, viscous, and fibrous media, providing reliable on/off control in heavy-duty industrial pipelines.
Available in carbon steel, stainless steel, and alloy steel, the valves support flanged, wafer, and lug connections. Optional automation includes pneumatic or electric actuators. OEM customization allows special materials, gate and seat configurations, and gear ratios to meet demanding process requirements.
