Knife Gate Valves Made in Tianjin China
Heavy-duty gate valves designed for slurry, pulp, and thick media where a standard gate valve would jam or fail to close fully, used in pipelines with high solids content or fibrous materials.

Model codes as they appear on our production drawings. Sizes and pressure ratings for each code are confirmed on quotation.
Buyers This Category Suits
- Wastewater treatment plant operators managing thick sludge and grit lines
- Pulp and paper mills requiring reliable isolation in fiber-laden process streams
- Mining and metallurgy facilities handling mineral slurries and tailings
- Power plants managing ash and fly ash transport systems
- Chemical and pharmaceutical plants processing viscous or particulate-laden media
What It Fixes on the Line
- Standard gate valves seize when handling slurry, pulp, or fibrous waste streams due to material buildup in the gate channel
- Valves with non-rising stems are difficult to verify open or closed position during operation or maintenance
- Inconsistent gate alignment causes leakage and premature seat wear in high-solids applications
- Lack of a single supplier for both small and large diameter gate valves complicates procurement for large projects
- Valves with fixed stems cannot be adjusted for wear or misalignment after installation

Knife Gate Valves FAQ
What is the difference between the KG001 and KG003 models?
KG001 is a cast iron knife gate valve without a rising stem. KG003 is a rising stem valve with a bevel gear drive, allowing manual operation and position visibility.
Can the knife gate valve handle abrasive or fibrous materials?
Yes. The knife-edge gate is designed to cut through fibrous and abrasive media such as sludge, pulp, and mineral slurries without jamming.
What materials are used in the gate and body?
The KG003 model features a WCB body and SS201 gate. The KG001 model uses cast iron for the body. Material specifications are confirmed on request.
What size and pressure range do these valves cover?
The knife gate valve series covers nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. Exact ratings per model are confirmed on quotation.
Are the valves certified?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.
Can I order mixed models in one shipment?
Yes. Knife gate valves, butterfly valves, check valves, and other families can be combined in a single container for project orders.
