The manual slurry valve is an essential device used in industrial applications to divert, combine, or switch the direction of media flow. As a type of gate valve, it features a knife-edge gate design that effectively prevents sealing failure caused by media sedimentation. This makes the manual slurry valve widely applicable in industries such as mining, steel, purification equipment, papermaking, sugar manufacturing, food processing, and power plant ash removal.
The valve is available in wafer-type and integral-type structures, allowing users to choose according to specific needs. In terms of actuation, it offers both manual operation and electro-hydraulic options to meet different operational environments and automation requirements. For sealing, the valve utilizes composite “U”-type and “T”-type structures made of advanced materials, ensuring a more stable and durable sealing performance.

| Integrated Knife Gate Valve | Features bidirectional sealing with zero leakage, capable of withstanding high pressure differentials. The full-bore design ensures maximum flow capacity. | 
| Groove-Free Seat Design | Prevents medium accumulation on the sealing surface, avoiding leakage and gate jamming caused by sediment buildup. | 
| Precision-Cast One-Piece Valve Body | Ensures superior strength and structural integrity. | 
| Elastic U-Shaped Seat Design | The seat is embedded inside the valve body and precisely fits with the gate plate. The smooth vertical movement of the gate reduces friction, greatly extending the seat’s service life while achieving reliable bidirectional sealing. | 
| Rubber O-Ring Seal | Embedded within the flange groove, making installation easy, connection secure, and sealing highly reliable. | 
| Wide Application Range | Commonly used in municipal wastewater treatment, papermaking, mining slag discharge, and other industrial fields. | 
The manual slurry valve is a type of gate valve used in industrial applications for diversion, convergence, or flow direction switching. Featuring a knife-type gate structure, it effectively solves sealing issues caused by medium sedimentation. It is suitable for various industries, including mining, steel, purification systems, papermaking, sugar production, food processing, and power plant ash removal.
We can design and develop according to the needs of our customers to meet the requirements of different clients.
